ER9-10K: Evnroll adds an ultra-high MOI putter to its lineup
Evnroll founder Guerin Rife saw the high-MOI mallet trend in professional golf and decided to raise the bar (appropriate, given his historical fondness for bars on his putters). Enter the ultra-high MOI ER9-10K Extreme mallet.
“I noticed more and more lately that many players on the PGA Tour are opting for high MOI oversized putter head designs,” Rife says. “They have to stand over a 4-foot putt worth $200k to $1m that will change their life. The pressure can be paralysing.”
According to the company, the highest MOI putters on the market are in the 5,000 range. As you might guess from the name, the ER9-10K has an MOI of 10,000.
In other words, as Guerin Rife says
“The ER9-10K is stability on steroids!”
To keep overall size down, the ER9 has milled 6061 aluminium body with hollow cylinders that run along the length of the head where steel weights are inserted. A range of short and long rod weights can be plugged in to dial in swing weight based on shaft length, grip weights and counter weights.
The ER9-10K also features Evnroll’s “Sweet Face” Technology: a unique mill pattern engineered to deliver uniform performance across the entire hitting area of the putter.
Additionally, the grip is geared toward enhancing MOI. The patent-pending Gravity Grip features a 70g, 10-inch steel rod that travels the full length of the deep V underside of the grip. This places 85 percent of the grip’s total weight in the fingers below the shaft, promoting a toe-up square face to the swing plane. At 120 grams, the Gravity Grip also acts as a counter weight.
The ER9-10K Extreme mallet will be available in three head weights according to shaft length (33 inches at 415 grams; 34 inches at 400 grams; 35 inches at 385 grams) with hosel options of either plumber neck or short slant neck.
The ER9-10K mallet extends the full Evnroll product range to 11 models for 2018. Starting spring of 2018, all new models will join the existing product line-up, available in 33, 34 and 35-inch lengths with an MSRP of $329 for the ER1, ER2, ER2cs & ER3 and $359 for the ER1.2, ER5, ER6, ER7, ER7cs, ER8 & ER9.

Since our founding in 2005, the bedrock of GolfWRX.com has been the community of passionate and knowledgeable golfers in our forums, and we put endless trust in the opinions of our GolfWRX members — the most knowledgeable community of golfers on the internet. No other group of golfers in the world tests golf clubs as frequently or as extensively, nor is armed with such in-depth information about the latest technology.
Below are the results of GolfWRX member voting for the 2025 best driver, along with the vote percentage for each club.
Best driver of 2025: The top 5
5. Callaway Elyte Triple Diamond: 6.02%
Callaway’s pitch: “For golfers looking for a fast, forgiving, yet workable driver, the Elyte Triple Diamond features a tour-inspired shape and is the preferred model by most Callaway tour players.”
You can read what other golfers are saying about the driver in the GolfWRX forums, and see our launch piece here. Shop the Callaway Elyte Triple Diamond here.
4. Ping G440 Max: 6.86%
Ping’s pitch: “The most forgiving G440 model, MAX has a hotter face to generate speed and distance, and a lighter overall system weight with a longer shaft (46″) for faster clubhead speed, higher launch and longer carries. The Free Hosel and Carbonfly Wrap crown save weight to create our lowest CG ever and increase forgiveness while contributing to a more muted, pleasing sound.”

3. Ping G440 LST: 9.53%
Ping’s pitch: “LST is an especially good fit for faster swings, offering less spin and more control with a penetrating trajectory. A hotter face, lighter overall system weight and longer shaft (46″) deliver more speed and distance while maintaining tight dispersion.”
@phizzy30: “Not a fan of Ping drivers in general, but 440 LST takes the cake. It’s super forgiving across the face for a low spin head, looks and sounds good and the ability to make it play neutral or slightly fade biased through the hosel settings is very appealing.”

2. Titleist GT3: 16.55%
Titleist’s pitch: “The GT3 Driver offers Titleist’s boldest combination of power and personalization through adjustable performance. Dial in the CG Track to your frequent contact location to make your biggest drives even bigger while taking total control over flight and shaping.”
@mrmikeac: “I’ve been Anti-Titleist for years and years and years (outside of Vokey, of course). With that being said, HOLY BEGEEZUS the GT3 driver is an absolute NUCLEAR MONSTER! This thing blew my G430 10K Max out of the water in every single category. Forgiveness is the biggest thing that stands out of me, the 3 model has always been one of the less forgiving models in the past but this GT3 can take bad shot after bad shot and still end up in the fairway, I think a ton of that has to do with the adjustability, it’s actually effective. Feel and sound is perfect, that solid crack is so addicting to hear and when you hit it out the screws this thing can absolutely bomb it. Titleist, I’m sorry for doubting you. You have converted me.”

1. Titleist GT2: 22.91%
Titleist’s pitch: “Delivering impressive distance from any impact point, the Titleist GT2 Driver extracts maximum performance through a forgiving design. Get the stability and added confidence of a high-MOI driver without sacrificing speed.”
@DTorres: “The Titleist GT2 has proven to be the best driver of the year. Packaged in a classic profile, GT2 perfectly balances performance and forgiveness while consistently being a high performer across all categories.”

If the Putter, works better for you, than the one in your bag, and you can afford it buy it simples.
If it works for you forget the mathematics and logarithms of how it was achieved.

ER9 putter head = 400 grams
Gravity Grip = 120 grams
Steel shaft = 120 grams
Total weight = 640 grams = 22.57 oz. = 1.4 pounds ….!!!!
Golf ball = 1.62 oz..
Ratio of putter weight to ball weight = ~14:1 :-O 😮 :-O

“The ER9-10K Extreme mallet will be available in three head weights according to shaft length (33 inches at 415 grams; 34 inches at 400 grams; 35 inches at 385 grams)…”
33 x 415 = 13,695 gram-inches
34 x 400 = 13,600 gram-inches
35 x 385 = 13,475 gram-inches
All about the same first moment about the handle end … 😮

Oh… and the putter weighs nearly a pound (~15 oz.) which should be adequate to overwhelm a 1.68 ounce ball… but maybe it’s too heavy to swing back and stroke forward with a soft finger grip. Maybe it requires a strong ham-fisted grasp to keep under control while torquing otherwise the pendulum stroke will break down and go out of control…. ya think?!! 😀

High MOI is good for off-center miss-hits on the putter face, but it’s the enemy of the putting stroke because of weight imbalance in the hands. If you hit the ball on the putter sweet spot and +/- 1/2″ the excessive MOI is useless.
If you have an unstable putting stroke the high MOI is your enemy because it will further destabilize your putting stroke. You will lose control of the putter, plain and simple.
