Mizuno’s new, super-adjustable GT-180 driver and fairway woods



All the way back in August, we spotted a prototype “GT-180” driver from Mizuno that had a sole full of adjustable features.

Then, in November, Mizuno launched a ST-180 driver that had “wave-sole technology” in the sole that was used to push weight low-and-forward in the club head to reduce spin rates. But, the ST-180 did not have the adjustable features of the GT driver we spotted. So, we thought, where is this ultra-adjustable “GT-180” driver?

Well, Mizuno finally launched the GT-180 driver. It’s packed with all of the adjustability we expected, but now we have all the tech info. There’s also GT-180 fairway woods.

Read below for everything you need to know about the GT-180 drivers and the fairway woods, and see what GolfWRX members are saying about them in our forums.

Mizuno GT-180 driver

Mizuno promises extreme adjustability and performance optimization with its GT-180 driver. The club features a forged SP700 Ti face, implementing the multi-thickness face concept we’ve seen recently as manufacturers strive to maximize ball speed across the face. Two movable, 7-gram weights offer the full buffet of adjustability options, and the Quick Switch adjustable hosel allows for four degrees of loft adjustment and three degrees of lie toggling.

“With its wider range of settings, the GT180 can hold the key to squeeze out those last few seemingly unattainable yards,” says Bill Price, Custom Fitting Manager at Mizuno. “Being able to fine tune your launch angle and spin rate is the final element in the equation to find your most efficient flight.”

On the subject of how golfers should choose between GT-180 and ST-180 drivers, R&D Director David Llewellyn put it simply.

“Most players like to keep things as uncomplicated as possible – to stand there and give the ball a rip. The ST-180 is for them. Then you have players who enjoy the process of dialing in a driver and getting it optimized to the yard – that’s the GT-180. Everything else is very similar – playability, ball speed. Chose a model based on your attitude to the game – it’s not about ability.”

GT-180 drivers will sell for $500, and they come stock with Mitsubishi’s Kuro Kage shafts, although other shafts are available at no upcharge.

Mizuno GT-180 fairway woods

Reduced spin, maximum adjustability, and no ballooning if you’re in the upper range of the swing speed scale. Such are Mizuno’s promises with its new GT-180 fairway woods. The company continues to refine its Wave Sole and sliding weight system, pairing the technologies with a thinner, 1770 maraging steel face.

Mizuno’s GT-180 fairways woods offer 17 grams of total sliding weight, as well as the same Quick Switch hosel as the driver (four degrees of loft adjustment, three degrees of lie). A TS (tour style) model with a more compact, lower-lofted head, is also available. The fairway woods will sell for $300 apiece.

    How will it survive a sliver rating from GD club test? TIC of course…

    So how many of their Staff players will put it in the bag?
    As usual probably none, stick to making irons!

    Definitely will try this one. I love my JPX 900, but I wish it was just a bit deeper. I have it set to 7.5* with the supposedly lowest-launching 757-X, and am still living around 2500 RPMs. It’s really straight, and on average as long as my M1, but if this one is a touch deeper, that may mean a buy.

      Btw, that lie angle chunk on the bottom is straight garbage. Removed mine and added an additional weight. Can’t believe they repeated that mistake.

        The chunk on the bottom is (I believe) for face angle adjustment – not lie.
        I quite like that feature as I need increased loft but don’t like closed face look at address.

    Both the ST and GT 190 drivers have forged SP700 Ti face inserts, but the question is what is the metallurgy of the driver bodies, the crown and sole?
    My guess the bodies are a cast aluminum-titanium matrix to achieve the complex shapes in both driver models.
    The Al/Ti matrix is like 99% aluminum and 1% titanium, and is usually found in really cheap jumbo drivers at WalMart.

    This is just another ripoff of gullible gearhead golfers who think they are getting something special.

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.
