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.

This week, we have our Tour Photographer, Greg Moore, on the ground at the OccuNet Classic at Tascosa Golf Club in Amarillo, Texas, for the 14th event of the 2026 Korn Ferry Tour season. With that, we see some great things in the Lead Tape Report as we roll into Amarillo.
Joel Thelen
Monday Qualifier, Joel Thelen is in the field this week. He has played on the Korn Ferry Tour for a full season in 2023, and he is back in action this week. A couple of clubs caught my eye this week in his bag.
First off: His trusted Titleist 816 H2 hybrid. This club came out in October of 2015, and it still remains strong in the bag. Also, take a look at this Odyssey White Hot OG 7, putting a capital S in the 7S model. This custom neck has some impressive lean for an arm-lock-style putter. The bottom of the putter is covered in tape for optimal weighting.
Mitchell Meissner
Taking a look at Mitchell Meissner’s bag this week, we have some great lead tape coverage. Top to bottom working from fairway metals, irons, and wedges. We can see on the short irons and wedges that there is tape at the base of the grip, adding a little counterbalance. Along with that, some tape on the short irons and wedges as well. Moving to his putter, he rolls the Odyssey 7 Bird putter. Meissner putts left-handed and strikes the ball right-handed.

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.
