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.

    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.

Mizuno announces new JPX 919 Tour Forged irons are coming August 29 (via cryptic Twitter post)



While cryptic, it does appear Mizuno is announcing via Twitter that its new JPX 919 Tour irons are coming on 8/29/18. One would have to assume that means they will be launched on 8/29, not actually hitting retail on 8/29, but that remains to be seen.

We recently spotted a number of new irons on the USGA conforming list, including the JPX919 Tour irons pictured above, JPX919 Forged and JPX919 Hot Metal irons from Mizuno. So it’s likely that the JPX 919 Tour Forged irons won’t be alone in the JPX 919 family when they hit retail.

The JPX 919 Tour iron specifically pictured in the Tweet above seems to be the replacement for Mizuno’s JPX 900 Tour irons that Brooks Koepka used to win this year’s U.S. Open and PGA Championship. Learn more about the original JPX 900 Tour design from Mizuno’s Chris Voshal on our Gear Dive podcast.

Diving a bit deeper into the picture from Mizuno’s Tweet, it appears the JPX919 Tour irons will utilize Mizuno’s familiar Grain Flow forging, and will be made from 1025E; that’s based on the hosel stamping that says “GF Forged HD 1025E.”

Stay tuned for more info from Mizuno.

An Interview with T Squared putters, started by a high school golfer



I’ve coached high school golf for over 15 years, and I thought that I had run out of “firsts.” Then, Anthony Tuber, one of our varsity six, told me that he builds putters. “Sure,” I thought. You purchase the components and assemble putters. Nice hobby to have. “No, coach, I build them from scratch. We have milling machines.” If that doesn’t catch your attention, not much will.

As a coach, you encourage your golfers from a base of experience, but I don’t have any club-making experience! The last time I played around with metal was in middle-school metal shop. In this particular case, the student is the coach, and the golfer is the teacher. I’m now the proud owner of a T Squared putter, and continue to be the proud coach of Anthony Tuber. He might be the next Bob Vokey, or Scotty Cameron, but for now, he is a varsity golfer and high school student. Oh, and he happens to make putters. Rather than write a review that might be perceived as biased, I decided to do a straightforward interview with T Squared Putters. If you want to learn more, visit the company website, or follow them on Twitter and on Instagram.

Question 1: What type of research and field testing did you do, prior to building your first putter?

Prior to making our first putter we bought a bunch of putters to see what we liked and disliked about them. Then we took those putters and tested them to figure out which roll we liked the best. The roll is determined by the weight of the putter the length and the groove pattern. After we completed the testing we drew up a design and shortly after that we had our first prototypes. We then tested those prototypes and they rolled exactly how we wanted. Time went by while we used these first putters but then we really wanted to see the competition. We went to the PGA Merchandise Show and that’s where we found out that we had a superior putter.

Question 2: Is there a style of putter that you like, that perhaps served as inspiration for some of your designs?

We bought and tested dozens of putters but two putters caught our eye and those putters are the Scotty Cameron Squareback and the Scotty Cameron Newport 2 Notchback.

Question 3: Can you tell us a bit about the materials/components that you chose for T Squared Putters?

We use American-made 303 stainless steel in all of our putters, but we also we use 6061 aircraft aluminum for the insert on the 713i.

Question 4: How do you balance your responsibilities and commitments, with your T Squared production?

During the school year academics are my number one priority. Over the summer I have been balancing my Tsquared putters work while working on the progression of my golf game. Fortunately I have a team that is very supportive of my vision for T Squared putters.

Question 5: Any chance we will see a mallet-style putter from T Squared?

Yes, we are currently testing other mallet putters to determine the most desirable features for our mallet putter. We are anticipating a prototype soon.

Question 6: Are you a better putter now that you know so much more from the design and production side of putters?

Yes, I have an entirely different perspective when I stand over every putt.

Question 7: How do you get the word out about the quality of your putters?

We have been very active on social media. The golfers that are currently using a Tsquared putter have been spreading the word. We have also been attending local golf tournaments to establish our brand.

Question 8: Do you hope to make a career of this venture, or do you envision it as a step along the path of a 21st-century businessman?

Yes, as golf is my passion I hope to take Tsquared putters to the next level. Golf will always be a part of my life whether it is professionally or recreationally.

Question 9: Finally, what question haven’t we asked, that you wish we would? Ask it and answer it, please.

I haven’t been asked how this process has affected me as a person. As a 17 year old I have a new appreciation for patience, persistence and hard work.
