About a month ago, we unveiled the new 2018 EVNROLL models. The new models feature both traditional designs, like the Anser-style model 1.1, and more niche-market offerings, like center-shafted versions of their popular ER2 and ER7 models.
In addition to unveiling those models in that article, I hinted at the end that Guerin had one more model coming – the ER9 – and that you’d see and hear all about it at the PGA show. Well, the show starts today, and that means that we can finally unveil the EVNROLL ER9!
Today at the 2018 PGA Show, Guerin Rife, the mastermind behind the unbelievably accurate EVNROLL putters, will be unveiling a new putter model, the ER9. It’s a nearly unbelievable putter, and definitely deserving of a bit of PGA show fanfare.
Massive MOI
The ER9 represents an exercise in extreme putter MOI. How extreme? Well, most putters are considered high MOI putters when the MOI reaches the 5,000 mark. The MOI value for the MOI is 10,000. Yes, 10,000 of anything is a lot (visualize 10,000 kittens), but
“What the heck is MOI?”
The short answer is that MOI stands for Moment of Inertia, and it is one of the quantifiable characteristics of an object that can affect both its rotational and angular momentum. Essentially, the higher the MOI value for an object, the more that object resists rotation when moving.
In physics class, I learned this concept through observing a figure skater. Envision an ice skater spinning with arms extended away from his or her body. When the arms are then pulled in to the body, the speed of the rotation increases. Simply put, the skater with arms extended has a higher MOI, and thus spins slower. Of course, MOI can also be discussed with fancy numbers and symbols, but thinking about the skater helps me to understand MOI in more practical terms. So how does all of this MOI stuff relate to putters? Here’s Guerin to help us out.
Can a putter be too stable? Is there such thing as too much MOI? And what the heck is MOI? Short answer is… “an object’s resistance to twisting”. For a putter, that translates to a rock steady swing path and an enlarged area of forgiveness off the face. So all you have to do is aim. This is achieved by moving weight away from the center of mass.
So in a way, the putter parallels the skater. When the mass is positioned toward the perimeter of the putter, like a skater with arms extended, rotation is decreased. Less putter head rotation means more stability, which should translate to a more stable stroke.
How did the ER9 get to 10K MOI?
To achieve high MOI requires designing a big, really big putter head that resembles a frying pan on the end of shaft. It needs to be a blend of aluminum and steel. Steel is about 3 times heavier than aluminum so it’s the key to achieving the high MOI. The ER9 has a milled 6061 aluminum body that has a hollow cylinder along the extreme heel and toe that runs the length of the head from face to rear to receive sizable steel weights. This keeps the overall size down (somewhat) and achieves and incredible 10,000 MOI.
The ER9 is a multi-material design, reflecting a combination of light-weight aluminum and heavier stainless steel. The bulk of the putter is made from aluminum, allowing the relatively large putter body to be relatively light. The stainless steel perimeter weighting of the putter moves the overall relative weight of the putter to the edges, effectively “extending the skaters arms” weight-wise. Increasing the relative weight at edges of the putter boosts MOI, and leads to less rotation. You are going to be an MOI expert by the time we are done today…
Specifications: EVNROLL ER9-10K
- Head Material – 6061 Aluminum
- Hosel Material – 303 Stainless Steel
- Cylinder Weights – 303 Stainless Steel
- Shaft – FST Stepless, .370” Tip
- Grip – Custom Evnroll Gravity Grip
- Available in 3 Head Weights:
- 33” @ 425 grams
- 34” @ 410 grams
- 35” @ 395 grams =
- Hosels – Plumber Neck or Short Slant Neck
The ER9 is a Beefy Beast
Maintaining pleasing aesthetics can be challenging when designing high MOI putters. Trying to get the weight to the edges will likely necessitate some visual compromises.
The ER9 gets around some of this by using the different metals, but the desire to position weight away from the middle and toward the edges mandates those edges be a good distance from the center of the putter. Again, you lose some of the aesthetic freedom when your goal is to boost MOI as high as you can. Figuring out how to make it not look like a “frying pan on the end of the shaft” can be challenging.
The ER9 is a big boxy beast. For comparison, I’ve included a shot of my EVNROLL ER5. I’ve never considered the ER5 a small head, but the ER9 just towers over it.
Though its profile is rectangular, the ER9 is more than a brick on a stick. If you look closely, you will see areas where the aluminum material has been rounded or removed altogether. This improves the aesthetics and provides a means to remove weight from the center, thus boosting the proportion of weight on the edges and increasing the moment of inertia.
The widebody cavity and its three associated sight lines break up the blockiness a bit and should help you to square the putter to the target line at address. The characteristic EVNROLL double sight dots on the top edge also aids with alignment.
An alignment scheme that helps you aim correctly, paired with the stable swing from the staggering MOI, should be a solid recipe for making putts. The ER9 has some other features that should also help your putting.
Roll Technology
Like all Evnroll putters the ER9-10K features Sweet Face Technology that produces consistent distance and eliminates dispersion. However because of the extreme stability created by the 10,000 MOI the parabolic grooves have been dialed back to produce the same energy transfer and gearing effect for off-center hits.
The grooves have been tweaked a bit, but they are still the Sweet Face Technology grooves that make the EVNROLL putters so user-friendly. To refresh your memories, these are the grooves that can help correct not only for distance with off-center strikes, but also accuracy as heel and toe strikes will track back toward the target line rather than away from it. They didn’t twist the face to do this, just made it groovier. Dibs on the twisted face putter patent…
Feel Balanced
I think the word is “serendipity”. It when you head out into unknown territory and fate delivers you and unexpected bonus. The ultra light aluminum body with long heavy steel weights running along the length of the heel and toe allows for 15% more head weight. Yet ER9 swings effortlessly along the swing plane and “feels” like a much lighter swing weight. Having the lighter feel with the heavy head weight delivers excellent distance control and deadly accuracy.
Counterweighting putters have been a huge help for many golfers. The heavier than normal head, coupled with a heavy grip, or weighted shaft tip, promotes a smoother stroke. It’s been a few years since the (IMHO silly) anchored putter ban, and many formerly anchored player are now using counterbalanced models. It’s not the answer for all golfers, but for quite a few, it is the answer to putting woes. Many golfers have found the counterbalance putter to be the only thing that cures the yips.
Gravity Grip
Even the grip on the ER9 has high MOI. The patent pending Gravity Grip is made buy Evnroll and features a 70 gram, 10” steel rod that travels the full length of the deep V underside of the grip. This places 85% of the grips total weight in the fingers below the shaft promoting a toe-up square face to the swing plan. At total weight of 120 grams the Gravity Grip also acts as a counter weight for additional head weight and even more overall stability.
This new EVNROLL grip was a fun little surprise when I opened the ER9 box. It is a weighted grip, helping to counterbalance the 400g ER9 head, but it’s more than that.
The shape is unique. It’s much more wedge-shaped than a traditional putter grip. When your fingers curve around the bottom of the grip, your palms end up sitting reasonably flat against the sides. It takes some getting used to, but this grip allowed me to place my palms and back of hands much more parallel to the target line. It’s less of a “grip” action, and more of a “hold” if that makes sense.
Although it is a weighted grip, that too is a bit unusual as the weight in the fingers feels different than it does in more butt-weighted grips. You feel it in your fingers as opposed to the back end of the club, or inside of your clenched hand.
I’m not sure what my opinion is about the gravity grip. It feels nothing like my usual grip, and that’s a bit disconcerting, but not necessarily bad. After a bit more acclimation, it’s possible that what I now feel as different could transform into a feeling of better. Maybe not, but I’m not comfortable making a final decision on this one just yet. If nothing else, the unique design definitely merits more exploration.
Slant Neck Option
You may have missed in the list of specs, but you can also get the ER9 in a slant neck configuration. I played around with swapping the necks back and forth, and I do prefer the slant neck. Not totally surprising since most of my current gamers feature the same design. Fingers crossed that EVNROLL makes that neck an option on the ER1.1 or ER2.
The Beast is Released
The ER9 will not appeal to every golfer especially the traditionalist. But for those who absolutely, positively want to make every pressure putt the ER9-10K will deliver.
EVNROLL knows that the ER9 will not be everyone’s must have new putter, but there will be a segment of the golfing public that will wonder how they ever putted at all before bagging the ER9.
It’s a big thing, with the MOI numbers to match its hulking profile. I’ve talked to some other putter makers who believe that above a certain point, boosted MOI is a diminishing returns investment, particularly for looks and even for forgiveness. Time (and testing) will tell if the 10,000 MOI hits the stability sweet spot, or if it is just too darn huge.
I don’t know if the ER9 is immediately going to become my new gamer, but I love that it exists. I like to see putter makers push the design envelope here and there. Even if the ER9 ends up being just an exercise in engineering, it’s a hugely valuable exercise as I’m sure some interesting new design concepts will emerge because of it.
We all win in this story. Some win this season as they bag the ER9 and putt better than ever before, others may end up gaming some upcoming EVNROLL putter specifically because of what was learned and incorporated from the ER9’s development.
Call it a brick on a stick if you need to, but we all benefit from these boundary-pushing, bold adventures in gear design.
Juan
3 years agoHi there… you announced this putter heavily in May, however no review came afterwards, neither did it compete on Most Wanted… any reason??
Thanks,
Juan
Alex
3 years agoI went into their office in Carlsbad and got fit. Tried all the putters and decided on the ER9. I really like it. I’m used to a counterbalanced putter so this was the easy choice.
The big difference I noticed is that I had a mishit on a putt and I yelled out, crap missed it, and my playing partner noticed it kept going toward the hole for an easy 2nd putt. My old putter would of made it a 3 putt.
My only complaint is that they didn’t ask me if I wanted the red gravity grip which I would of wanted, didn’t realize there is a red until I saw here…haha
Tom Reeves
3 years agoWell, I got one today. It is amazing stable through the swing. I imagine that miss hits have some measure of correction but I failed to miss hit it.
On less than 20 foot putts, it’s a big improvement over my odyssey. On longer lag putts, it’s going to take some time to get used to. Definitely need to swing longer or hit the ball harder to transfer enough energy to the ball. But, the nice thing is that swinger longer/harder didn’t result in miss hits.
I’ll check back in a month or so for a more detailed review.
Javier
4 years agoJust curious, any description on what it feels like? I couldn’t even imagine what something like that would feel like.
Jeff J
4 years agoI like the innovation. Of course, it should have been named the ER 10 or ER X to commemorate the MOI and link the technical aspects for the customers!
Tim Carson
4 years agoLove reading about Evnroll putters in Mygolfspy but I can’t overcome a basic logistical problem: Although I live in the golf-rich Philadelphia suburbs, the closest outlet (store or club) carrying Evnroll (at least as of last year when I emailed with their marketing people) is a two-hour drive away (a PGA Store in North Jersey). No, Mygolfspy rave reviews notwithstanding, I won’t buy a putter before trying it out! Has Evnroll solved this problem?
Myron miller
4 years agoOne issue> Max length of shaft is 35″. And for those of us tall, that’s not long enough so I’d have to extend it with shaft extender which distorts the balance of the club.
Until they decide to make putters for us tall people, it’s not an option for me. Bending over hurts my back after a while. that’s what happens with a 35″ putter that i use at times.
Steven Racine
4 years agoI used use, & still have, the Ping Doc 17. I wonder what the MOI on that is. Forget the brick. How bout a skillet on a stick.
KP
4 years agoThe grip looks similar to the Lamkin FlatCat that I currently game on the original little brick on a stick–the Ping 1-A. Great putter that I bought brand new for $100.
brian
4 years agoI don’t understand why my comment didn’t post??
This is exactly the same stuff as Bettinardi’s 2014 BB55!!
Look similar to the new Antidote 2 from Bettinardi as well.
Lyle
4 years agoTwo simple questions:
(1) Does anyone know if it is face balanced?
(2) When the ER9 is placed on a flat surface, does the face want to turn open like the ER6 does?
Charlie
4 years agoThere is a good argument to be made for high-MOI putters. But then, like yesterday, I watch Tiger, using his low-MOI blade, knock that 70 footer to 18 inches or so on his last hole to make the cut. Many other pros use low-MOI putters. Perhaps the pros don’t benefit as much from high-MOI putters as amateurs.
ole gray
4 years agoI’m looking forward to seeing how this big boy stacks of in the Most Wanted list
Roy
4 years agoIn my opinion the ENROLL putters are the best ones on the market today! I made the switch from a Scotty Cameron last year and have seen my putting stats continue to improve!
Brian
4 years agoThis just looks completely like Bettinardi’s 2015 BB55.. Same idea here.
Well, mixed with the look of Bettinardi’s 2017 Antidote 2.
Dave S
4 years agoAs someone who currently games the Ping Ketsch Heavy, this is intriguing. I do think that Evnroll has developed real a technology advantage over other manufacturers, which in this day and age, is a real accomplishment. That said, I bought the Ketsch b/c of it’s performance in MGS Putter testing (and after personal in-store testing), so I’ll be waiting to see how it performs in this year’s testing against the Ketsch. The cost is significant, but if it really can help you sink more 5-10 foot putts (the distance that truly separates amateurs from pros) then I’m all for it.
Mike Hallee
4 years agoNot loving the looks or the feel, I am sure the MOI is high!
Matthew Merrell
4 years agoI loves Evnroll. The er7 has helped with my yips. This is an ugly beast. I can’t wait to give it a roll.
C
4 years agoIs it just me, or does that first picture make the hosel look adjustable? It could be nice to slide the hosel forward or backward on a track and even rotate it about the face.
Tom Harris
4 years agoI have used the ER2 for two seasons now and it has been the best putter yet. However, this looks very interesting and I may have to give it a try! Evnroll makes great products. It is also fascinating to me that most of my friends don’t hesitate to shell out $500 to $700 for a driver that they use maybe 12 to 14 times a round and yet won’t spend $400 for a putter they would use 30 times or more in the same round!
Dan
4 years agoTom, please give me first right of refusal if you bag your ER2 for this new ER9.
Thank you
Camryn
4 years agoI really like the look of it. Then again, I’m the rare one who enjoyed the odyssey havoc putter, as well as the Futura x. Can’t wait to try this out. Just sucks Nashville doesn’t have a distributor.
Bearded Flatstick
4 years agoI hope Evnroll plans on using a slant neck for their other putters as well. That’s the only thing that has kept me from purchasing one.
W.B. Neal
4 years agoIt looks good but I don’t see anything about center shaft availability. I am not about to give up my center shaft.
Spitfisher
4 years agoI loved the taylormade daddy long legs, I believe that had face technology ( pure roll) and if I ma not mistaken 8500+ moi
shortside
4 years agoQuite the confidence builder I say. It’d take some work to swing and miss with that rascule.
James T.
4 years agoTo make room for it in your bag you’ll have to take out two other clubs.
Tom Duckworth
4 years agoWow giant! I couldn’t play with one that big it would be too distracting the ER5 looks nicer. I wonder why tungsten couldn’t be used and maybe make the head a little smaller.
Michael
4 years agoWill that grip be available to swap out the stock grip on my ER6?
Mike Wales
4 years agoWill this putter be in the most wanted testing this year?
bearded_flatstick
4 years agoI really hope they bring the slant neck to their other models. That’s the only thing that’s kept from purchasing an Evnrol putter.
LeftyBradd
4 years agoLove the look of this, I cannot believe how much bigger it is than the ER5. I have one of those as well and love it. I have never putt better in my life than with my Evnroll. I seriously must have told 50 people about them. So the big question…does it come in lefty? I might have to give it a try.
Peter Swick
4 years agoWasn’t the Cure RX line of putters capable of well over 10K??
Paul
4 years agoHeck yeah!!!! I’d play it! I’m going to have to hold-off until March to try it before I buy it, especially because of the grip.
I was one of those people who could have played the Ping Eye. I will have no problem putting with something this large, especially if I sink more putts as a result!
Robert Dwyer
4 years agoOMG ! It’s a chunk of metal on the end of a stick get over it. If you are a half decent putter you could tie a flat rock to a stick and play golf. How about we bring the game back to earth and just play.
Uhit
4 years agoI tried this with a piece of wood, and it felt good!
Robert Dwyer
4 years agoI knew it would work! Great to see other who can play golf and maintain a sense of humor!
Greg
4 years agoI am used to mallet, heavy head putters with counter-weight grips and like them a lot. I think I could not go back to blade style putter now. This ER9 looks like a very decent piece of technology.
Ray
4 years agoThat’s Bigger Than My Driver!
Alex
4 years agoCure has been doing this for years!
J-Full
4 years agoExactly! I’ve had multiple Cure putters. I swear by their adjustable models. Especially the ability to alter the lie angle on days where I can’t seem to get comfy over the putt.
I tried to play with a maxed out MOI cure putter but it was TOO heavy. Ball definitely stayed on line but i was so damn nervous standing over the shorties
Uhit
4 years agoBeside, that I want to try a Evnroll putter this year, I can not understand the buzz because of 10k MOI…
…because my CURE RX5 has a MOI between 8500 and 18000:
https://cureputters.com/pages/high-moi-comparison-cure-vs-others
And it has a higher MOI at the same weight, than the ER9.
Thus, neither 10k MOI, nor the design impress me in this case…
…however, I am keen to give some of the other Evnroll offerings a try.
Terry M McDowell
4 years agoYou are forgetting that Cure putters do not have the revolutionary face technology that Evenroll has.
Uhit
4 years agoNo, I didn’t forget, which is why I want to take a look at them this year.
However the RX5 has such a high MOI and has a very large face,
that I can put two balls side by side and hit them both at the same time into the same direction…
…and they end in pretty much the same spot…
…thus I am not sure, if it is possible to get any better than this – because it is already perfect.
However, maybe one of the smaller looking Evnroll models may give me similar results to the huge RX5.
MG
4 years agoDoes this putter and other high moi putters work for an arc stroke? Or would being so stable make that type of stroke difficult? Also, will this be in the best putter testing this year?
Greg Johnson
4 years agoContinue to be intrigued by Evnroll technological advancement in putters. Getting fitted is still the best advice for choosing a putter. If fitters in my locantion had Evnroll putters to try, I might own one. Until that time, que sera, sera. Go Ping!
Paul
4 years agoNothing that Bobby Grace hasn’t done with his F-22 and F-35 putters
Jason G
4 years agoNot the best looking putter I have seen. But have been very impressed with the performance of my ER2, so I definitely be willing to give it a try.
CT
4 years agoCan I be in the test group? I loved my ER6. I would love to game this.
Dennis
4 years agoThe description of this putter reminds me of the “heavy putter” by Boccieri Golf. Heavy head with a counter balanced grip. Always liked the feel of the heavy putter and still use it today, but for some reason, they never got a lot of traction in the market.
Pete S
4 years agoWhat is the best place to get fit for an evnroll putter?
Jason G
4 years agoThe best place is at their HQ in Carlsbad, CA. Awesome experience.
Don
4 years agoSign me up. It strangely does not look that bad in the photos. I am more than willing to test it for you guys.
Mark
4 years agoI have been playing the ER2 for over a year now (thanks MyGolfSpy!) and am totally sold on the technology.
I’ve always gone with a blade style putter and pretty much ignored the mallet market (although I did test the whole ER range). Because of the results from the ER2, and the fact there is a slant neck option, I will make it a point to test the ER9 with an open mind.
Thanks for the info and looking forward to some testing!
FrankS
4 years agoI just got the ER6 in a black color actually wanted it in red ….the retailer ordered in the wrong color….was a Criatmas present to myself. I have many putters Scotty 7, Guerrin-rife hybrid, Taylor Made spider one of the first models. All my putters have either been cut or made to between 29 and 31″ my New Er6 is 30″ it has been made 72 degrees lie and 2 degrees of loft, the grip has an extra wrap, I have putted with it a few times as I just got to Fl. Seems to hit putts much straighter, is that possible?
JW
4 years agoThe Star-Trek putter is here!!
Rich
4 years agoI posted this in the “Evnroll First Look” article but didn’t get a response:
I own an ER2. Bought it sight unseen after the Most Wanted article. That said, the statement about the ER9 is strange.
MGS, please answer these questions: Is there any financial arrangement between Evnroll and mygolfspy? Is mygolfspy compensated in any way by Evnroll? Does mygolfspy have any sort of ownership piece of Evnroll?
The statement from Evnroll that the ER9 is being introduced by MGS makes me think yes. Why would an independent review website be the only website introducing a new product? Why would Evnroll want it to be exclusive to MGS?
Terry M McDowell
4 years agoMGS is totally independent and has not nor will not ever accept money from a manufacturer. Moving on.
Rich
4 years agoDo you work for MGS? I don’t see your name on the “Our Team” page.
Terry M McDowell
4 years agoNo I work for MSG.
Nick
4 years agoHow do Vice and Evnroll get ads on your webpage? Do you donate the space to them because they donated clubs to you?
Love the site bye the way.
Johnny Cowboy
4 years agoIt is no different than Ford unveiling their new truck at the Detroit Auto Show
ED
4 years agoI think it is mutually beneficial to both parties. Evnroll got massive exposure from the MGS putter test results, so now they are returning the favor by giving MGS an exclusive on the new putter release.
ChrisK
4 years agoI’m pleased with my current MLA putter. That alignment trick they do with those that white band at the top of them is really impressive; i can really tell if i’m lined up correctly or not. We won’t discuss the actual stroke i impart on it though 🙂
Art
4 years agoIntriguing that Evnroll has jumped in to the “brick on a stick” pool. Will you be testing other super-high MOI-ers along with it? Cure and Orion putters come to mind, which are somewhere near 20k on the MOI measurement.
Sage
4 years agoNow Bettinarti BB-55 has a little brother.
Ryan
4 years agoMy sentiments EXACTLY!!
P.T.
4 years agoHow much will it cost??
Sean Gallagher
4 years agoReminds me of the Bettinardi bb55.
ChristopherKee
4 years agoThis is very Cure Putter-esq in the material and weighting. I know it worked well fur Cure when you loaded up the weights, so I’m sure this will do well in the MOI department.
Would love to see the interchangeable neck’s on the entire line though, sometimes I don’t want a new putter, just a different close rate for where my stroke is at. Being able to go from plumber to slant would be awesome.
Ell
4 years agoThis “big” putter doesn’t come close to the size of the putter that Jack Nicklaus used to win the 1986 Masters. After a few years it disappeared from his bag and from the shelves of retail stores. What’s the retail price? Over $400? Why not invest in a roll of lead tape and experiment with adding it to the toe and heel of a putter?
Regis
4 years agoYou’re referring to the Response. At the time it was viewed as a big putter but trust me it was nowhere near as big as the TM Spider let alone this bad boy. Not even close
strokerAce
4 years agoWOW that’s big… good thing the color is a muted gray… imagine how big it would look if it was white or silver.
I’m curious about the grip…does Evnroll plan to add it to any of their other putters or is this made specifically for the 10k due to the extreme weight of the putterhead?
Padraig Doyle
4 years agoI’m amused at the ‘technical’ reasons given by your readers for not wanting the new Evnroll ER9. What they don’t have the humility to admit is ‘I can’t afford it’ !
Keith Finley
4 years agoHi Dave,
Can you guys test the Evnroll face for heel vs toe gear effect? On visual, I can see toe correction but no noticeable difference in heel vs center
Mitchell
4 years agoThis is not the first putter with over 10k moi, the Cure rx5 can be configured to have up to 18 k moi.
MattF
4 years agoStating the bleeding obvious, that thing is HUGE! I just don’t know that I can get over the side so I’ll just keep lusting after the ER1.
MattF
4 years agoSize not side.
KevinE
4 years agoI’m very happy with my putter. On a whim, I’ve tried a few of the EVNROLL putters. My opinion a very solid putter. This new one with the mammoth head is just too much for me. Looks and feels like I’m putting with a driver. The visual is just not to my liking.
