ER9-10K: Evnroll adds an ultra-high MOI putter to its lineup

Published

on

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.

    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.

    Only a desperate deluded hacker would want this pile/piece of junk. No tour pro would play this abomination unless paid-to-play. Stooopid …!!!!

    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.

Tour Edge unveils all-new Exotics mini driver

Published

on

Tour Edge Golf has today introduced the all-new Exotics mini driver, engineered to deliver a powerful combination of speed, control, and versatility in the long game. 

The Exotics Mini combines a titanium face with a stainless-steel body in design to balance ball speed with stability and control, creating a versatile option at the top end of the bag. 

At the core of the design is Tour Edge’s proprietary Combo Brazing technology, a high-precision thermal bonding process that seamlessly fuses a titanium cup face to a stainless-steel body into a single, continuous structure. By eliminating energy loss found in traditional multi-piece constructions, Combo Brazing is designed to deliver faster face response, more efficient energy transfer, and a uniquely powerful yet controlled feel.

The multi-material construction also allows mass to be positioned lower and deeper in the head in a bid to increase stability, while the thin titanium face is engineered to maintain ball speed across a wider impact area.

“While the initial goal was to enhance control and versatility in the long game, Combo Brazing ultimately drove measurable gains in ball speed and distance within the mini driver category. In robot testing, we’ve documented higher ball speeds, higher launch, reduced spin, and increased carry and total distance compared to leading models.” – Vice President of R&D Matt Neeley

In addition to distance performance, the Exotics mini emphasizes forgiveness through a heavier stainless-steel body that shifts mass toward the perimeter. This configuration increases MOI relative to traditional all-titanium mini drivers, helping preserve ball speed and directional stability on off-center strikes. Paired with Pyramid Face Technology from the Exotics metalwood line, the design is intended to support consistent speed across the face.

To further enhance MOI, a lightweight carbon fiber crown frees additional mass that is strategically repositioned low and deep in the head in design to improve stability and promote optimal launch with controlled spin.

“We designed the Mini to be about five millimeters shallower than other mini drivers on the market. That change improves playability off the deck. From a clean fairway lie, it can function as a strong 3-wood alternative while still providing control off the tee.” – Tour Edge CEO David Glod

An adjustable hosel system allows for loft and lie tuning to dial in trajectory and shot shape, while a fixed 13-gram rear weight helps stabilize the head through impact to improve dispersion consistency. The Exotics Mini Driver is available in 11.5 and 13.5-degree lofts in right-handed models.

Pricing & Availability

The Exotics Mini Driver is available for pre-order beginning today for $399.99 USD at touredge.com, and will be available for purchase at retail outlets worldwide on May 22, 2026.

Srixon ZXi combo or TaylorMade P7CB/770 combo? – GolfWRXers discuss

Published

on

In our forums, our members have been pitting a Srixon ZXi combo against a TaylorMade P7CB/770 combo. WRXer ‘edutch22’ is on the hunt for a new set of irons and kicks off the thread saying:

“Looking at picking up a new set of irons and think I’ve narrowed it down to Srixon ZXi combo or Taylormade P7CB/770 combo. I am currently a 5 cap and allbeit I feel irons are my weakness. My miss is a little to the toe side. I am decently steep at 4-5 down. Always thought I am high spin but recently on trackman my 7 was spinning at 5800 roughly. 

My question or looking for thoughts on which one would benefit me more from a forgiveness standpoint? Or is there another iron is should be looking at entirely? I only get to play about once or twice a week, if I am not playing a 2-3 day event. Thanks in advance.”

And our members have been sharing their thoughts and suggestions in response.

Here are a few posts from the thread, but make sure to check out the entire discussion and have your say at the link below.

  • manima1: “You just can’t go wrong with Srixon ZXi7.”
  • MattM97: “You have to hit them to know, the V-Sole on the Srixon can be make or break for many.”
  • dmeeksDC: “P7CB is more forgiving for me than ZXi7 because my main miss is low middle and the P7CB still flies and spins great on that miss. These are both really nice irons but I like the P7CB more than the Zxi7 and the P770 (or P790) more than the Zxi5. The Srixons are larger so if that gives you confidence that is the way to go. I don’t feel like I get any benefit from the V-sole and the P7CBs live up to their high Maltby forgiveness rating so the TaylorMades have been great for me.”
