Mizuno ST190, ST190G Drivers put woods front and center for “iron” company

Published

on

Mizuno Golf is about more than just irons; that’s the message the company is keen to drive home with its launch of the Mizuno ST190 driver and the Mizuno ST 190G driver.

In announcing its lowest spinning, most technology-packed driver in company history, with the 2019 Mizuno driver, the company seeks to position itself as one that has quietly innovated in the driver space for years, highlighting milestone technologies in the Ti100, T-Zoid, MP-001, and MP-600 in discussions around the launch of its latest drivers.

With respect to the specifics of the Japanese company’s most recent weaponry, the ST190 and 190G feature a forged Sp700Ti face (10 percent stronger than 6-4 titanium) with the company’s ultra-light Cortech structure, as well as a carbon composite crown. As with the ST180 series, Mizuno applies its Amplified Wave soleplate, which deforms on impact for better energy transfer between club and ball.

The weight of the carbon composite crown, 12 grams, allowed engineers to redistribute some seven grams of weight throughout the body of the club.

The Amplified Wave Sole effectively expands the ST190’s COR area for improved balls speeds across the clubface, according to the company, and better ball speed on off-center strikes in particular.

Mizuno fine-tuned the driver’s sound via Harmonic Impact Technology, adding internal rids for a more solid sound at impact.

Getting into the differences between the two models.

Mizuno ST190

  • designed for mid to low spin with maximum stability
  • features a single, factory-fixed 6g backweight that adds 300gcm2 MOI

Mizuno ST190G

  • Designed for low spin
  • Features Fast Track adjustability: twin seven gram weights on external tracks
  • Weights can reduce spin by an additional 200rpm and allow for draw/fade biases

“The ST190 marks a total change in how Mizuno approaches wood design,” says lead Mizuno golf designer Kei Tsjui. “We now start the development process with our tour players. The tour-tested molds then become our production molds. In the case of the ST190, this produced a high-speed driver with extreme low spin for the tour, but with the capability of increasing spin for lower swing speed players.”

The first PGA Tour player to game the ST190 was big hitter Keith Mitchell.

Says Mitchell: “Driving was my best category last year – I walked into testing to do ‘Cookie’ (Mizuno, PGA Tour Manager Jeff Cook) a favor, give him some numbers and leave. It turned out to be the easiest change I’ve ever made – on the one club I never thought I would switch.”

Specs and availability

The Mizuno ST190: driver will be available in 9.5 and 10.5 degree models, both adjustable by two degrees either way. 9.5 degree option only for left-handers.

The Mizuno ST190G: driver will be available in a 9-degree model only, adjustable by two degrees either way. Right hand only.

Shafts: Mizuno offers 26 shafts without upcharge. New options for 2019 include Fujikura Atmos Blue 5S, Atmos Red 5R, Atmos Red 5R2, Atmos Red 6R and Atmos Black TS 6S.

MSRP: ST190: $400. ST190G: $500

ST190 drivers will be available nationwide and in Canada in February.

    If you play these black mizunos you won’t go back… and your golfing buddies won’t turn their backs to you.

    Another driver for future EBAY sellers….unless your a single digit or better 3 or 4 yards for $500 is a big step…almost any driver from the last 6 years or so is going to work for you.

    Trying like Hell to be honest and transparent in 2019… so take this fwiw…

    I handle a lot of donated clubs. Always trying to get clubs to kids, and often get 10 Adult clubs for every USKG/TourEdge/XYZ junior club. In 2016, one of the younger outside staff guys swung my 905r w/o asking and w/o knowing you don’t do that, it hit the pavement, so now I’m needing a new stick and a week later a Callaway fti 6 w/ a real fuji speeder walked in. Yeah, square headed, TINGY, and if my ST180 launched at 11 spun at 24, the cally launched at 14 spun at 31. But, in early 2017 I needed to knock out my pat, and from January 1 to April 4 I hit 90% (+/-2%) of my fwys over a 120 shot sample size. On April 4 2017 I’m plotting along and the wind kicks up to 20, gusts 27. On side by side holes I hit it 205 v 330. I was educated enough to be dangerous regarding spin OTT and about a month after the only time guys say “Now you never have to play golf again!” , the ST180 was showing up ahead of time for reasons unknown. I volunteer to be the guinea pig for a driver fitting in our Teach The Teacher program and in short time the youngest assistant pro I’ve worked with had made the most INCREDIBLE W.O.O.D. adjustment to my lead hand @ address and I see 160 ball 11.5 launch and 2224 spin. Deuces to the launch monitor , I want to watch it fly outside. It’s 253 to the net, and generally speaking your apex has to be high and if you carry the net you carry it 280. I’m swinging it at 107, so I don’t need to tell you how unlikely I was to do that, and how immediately I scribbled ST-180 tensei blue gp tv full cord on the DOG’s Christmas list. And in the entire year of 2018, I struggled off the tee so much that I would give it away to the first person that wanted it. I’m absolutely the guilty party, the Mizuno ST-180 is and was a truly best kept secret for for guys that can’t hit it left to save their lives, and admittedly I did hit the best drive of my post-arthrodesis life to date with it on the nastiest par 5 I know of in DFW, but I will NEVER ever EVER ditch a fairway finding four cylinder for a driving range heat seeking missile ever again.

    Until someone asks me to hit the stick that Ping is dropping in March.

    And unless the Titleist TS starts curving off the face of the Earth, I am looking forward to seeing it in my bag in 2028, just like the 905r was a welcome sight for an entire decade of golf.

    Looks a lot like the 180 kept it is Black. Love the 180, and even like the Blue.

    I hear they are working on an even better driver called the S&X69oo prototype model… it’s a beast !!!

    I’m still shopping for 2018 drives at vastly reduced prices. If I can’t make last years models give me fantastic performance, then there is something rotten in the state of Denmark. 2017 models are okay too.

    Look really good, finally ditched the blue! Excellent array of shaft options and adjustments for a reasonable price! Unheard of so far this year!

    Mizuno going with a cortech face is too similar to Wilson’s new Cortex driver.

    • Forged MB

      Jan 7, 2019 at 12:08 pm

      Except for the fact that Mizuno had the Cortech face well before the Wilson Cortex was even a thought and the Mizuno is actually getting your play. Don’t see any CORrelation at all.

      See what I did there? 😉

    So, at first I thought Mizuno waiting to release this driver at the same time as Taylormade, Callaway and PING was a mistake and that it would be overshadowed by the big boy offerings. But, after seeing the lackluster new releases from Taylormade and Callawy, I think it might work out for Mizuno. These drivers look soooo good and the stock shaft offerings are far far superior to the other’s.

    So many good drivers on the market right now. Would love to give this a try.

      If you are searching for a soft and buttery feel, these Miz drivers should fit the bill. They are orqasmic good!

Talking with Alonzo Guess of Sunfish…and a look at the insane headcover they made GolfWRX

Published

on

We last talked with Alonzo Guess of Sunfish in November of 2017 after the Nashville-based company launched a custom headcover and accessory builder on its website.

The company has been producing custom headcovers, yardage books, and other accessories since 2013 when it entered the market with its signature wool headcovers.

We wanted to see what was up, and Guess was kind enough not only to answer a few questions, but to design a pretty incredible GolfWRX driver cover using some raw assets we sent over.

BA: What’s new at Sunfish since we last talked? 

AG: 2018 was a great year for innovation at Sunfish. We worked hard to develop new design and construction techniques, and it has been really exciting combining these new creative elements into one of a kind headcovers and accessories. 2018 was our eighth year in business, but it was probably the most significant in terms of innovation. We’re excited to see where we can go from here!

BA: Looking at your websites, I know one of the new things you developed is something you call Photoflux. What exactly is Photoflux?

AG: Photoflux is our proprietary high-resolution printing process, that gives us the ability to apply to our products anything from photos to complex patterns to intricate logos. The level of resolution and detail is truly unmatched, and can’t be achieved with embroidery. We apply it to our leather and Duraleather products, even our hand-made copper ball markers and divot tools! Those are really exciting, because we can make custom copper ball markers with full color logos, on demand

BA: How the heck did you come up Photoflux?

AG: A customer ordered a scorecard holder with his family photo to be embroidered on each side. We made the piece and weren’t happy at all with the result. The embroidery process couldn’t do justice to the photographs. It was clear that there were certain limitations to embroidery, and we were motivated to overcome them. After months of trial and error, long hours and strenuous testing against sun, rain, and wear, we developed the current process.

BA: What are ways the Photoflux process can be used?

AG: Photoflux is perfect for applying photos, but can also be used for intricate logos or family crests. Really any graphic element can be expressed accurately using Photoflux, including shading. Recently we’ve had fun developing custom patterns such as tiger fur and using them as stripes on headcovers. The sky’s the limit!

Photoflux is best in concert with other design techniques, such as embroidery, laser engraving, and precision cutting and sewing. The featured piece (shown in this feature) incorporates Photoflux, precision cutting and sewing, laser engraving and embroidery. The result is as much artwork as it is a functional golf accessory.

BA: What are the limitations of the technology…what products can you apply Photoflux to?

AG: It’s great for leather and Duraleather headcovers, putter covers, scorecard and yardage book holders, alignment stick covers, cash covers, valuables pouches, wine bags, barrel style tartan headcovers…and even copper ball markers and divot tools!

BA: Tell me about this headcover you made for GolfWRX. I suggested the use of a graffiti wall, a GolfWRX logo, and skeleton hand holding up one finger to denote one club/driver, and you really went to town!

AG: So for the headcover you have, we used Photoflux to apply the graffiti wall image to the top of the cover (did you notice the ‘GolfWRX’ spraypaint in there? We threw that in there for you as an Easter egg!). On top of that, we embroidered the skeleton hand. For the stripe, we laser cut the outline of a typical urban skyline, and laser engraved the chain-link fence pattern over the top, than sewed that down. The bottom portion is a Photoflux image of GolfWRX that you sent over.

With so many new ways to decorate and manipulate the materials, we’re really excited about combining it all for our fans and customers to create really unique products. We feel the sky is the limit, and we hope this headcover illustrates that.

New XXIO Prime woods, hybrids, and irons aim for lightweight power

Published

on

xxio-prime-feat

XXIO’s latest club offerings, XXIO Prime, looks to offer easy distance and easy accuracy for the moderate swing speed golfer, according to the company.

XXIO Prime woods

xxio-prime

XXIO Prime Woods feature a new re-designed hosel structure, and reduced stiffness at the tip of the driver shaft, which is designed to help moderate swing speed golfers to close the clubface through impact.

Forged from Super-TIX PLUS Titanium, the new cup face includes a sweet spot that is noticeably larger than previous designs, which aims to increase distance performance significantly. The Super-TIX PLUS Titanium Cup Face is thinner, lighter and stronger than previous additions, creating a maximum COR across the face, which aims to increase ball speed and distance.

According to Chuck Thiry, Vice President of XXIO USA

“The speed increases, higher launch angles, and draw bias of the new Prime will show immediate results from swing one. It’s legit lightweight power for the players that absolutely need it the most.”

Featured in the XXIO prime woods is the SP-1000 shaft, with TORAYCA T1100G carbon fiber and NANOALLOY resin, which creates a strong but lightweight club. Along with the lightness in the shaft, XXIO has made weight savings in the grip and club head, which aims to produce woods that are both fast and easy to swing.

The XXIO Prime woods feature an expanded toe and narrowed heel, a tungsten-nickel inner weight that is low and deep, a lighter hosel repositioned closer to the center of the face, and reduced stiffness at the tip of the shaft, all with the aim of offering golfers with maximum forgiveness from their woods.

The XXIO Prime woods will be available from March 1 and will cost $579,99.

XXIO Prime hybrids and irons

The new XXIO Prime hybrids feature an expanded COR and a lower center of gravity, which is designed to increase distance and ball speed while delivering a straighter ball flight.

The hybrids from XXIO contain a Forged Maraging Steel Cup Face which includes a large sweet spot which aims to increase distance performance.

Just as with the woods, the XXIO irons also feature the Super-TIX PLUS Titanium Cup Face, though along with this, they also contain a CNC milled speed groove, which significantly increases the COR, creating a larger sweet spot, designed to provide greater distance, ball speed and accuracy.

Both the hybrids and irons include the SP-1000 Shaft, with TORAYCA T1100G carbon fiber and NANOALLOY resin. The hybrids and irons also feature weight savings in the grip and club head, with the aim of increasing swing speed.

With an expanded toe and narrowed heel, plus a crown step that moves weight low and deep, XXIO claim that this is their most forgiving suite of Prime hybrids. While with two high-density tungsten nickel sole weights and an overall profile that is 3mm shorter than the previous model, the company also claims to have created their most forgiving irons yet.

Speaking on the new XXIO Prime series, Chuck Thiry stated

“XXIO Prime is, quite frankly, the most unique and beneficial product ever available to moderate swing speed players. Period. People might think that is marketing hype, but they simply haven’t hit Prime yet.”

Both the XXIO Prime hybrids and irons will hit retail stores on March 1. The Prime hybrids will cost $379.99, while a single graphite iron will be available for $259.99.

SPOTTED: 2019 Mitsubishi shafts

Published

on

2019-mitsubishi-diamana-shafts

The Diamana shaft line from Mitsubishi Chemical is probably one of the most iconic in the sport. Released in 2005, Blueboard, Whiteboard, and Redboard, were the first generation of shafts.

Photos of the full fourth generation Diamana lineup, offering new materials and technology, along with new names, have surfaced in the GolfWRX forums. Like previous generations, each color shaft offers different ball flight and spin characteristics.

“RF” is the highest launching and spinning in the Diamana line, offering high launch and mid spin, while the “BF” is the mid-launch and mid/low-spin model. Finally, the “DF” is mid/low-launching and the lowest-spinning shaft in the lineup.

All of the fourth generation Diamana shafts use updated technologies and materials that you would expect from a premium lineup. DIALEAD pitch fiber is helps reduce shaft deformation, while still producing exceptional energy transfer.

Each shaft contains MR70 carbon fiber that is 20 percent stronger than conventional materials and Boron fiber for its compression strength and shaft reinforcement. ION plating has been done before in the Diamana line, in vacuum chambers — silver alloy ions are bonded to the shaft to give it a chrome-like finish that can’t be replicated by paint.

See what GolfWRX Members are saying in the forums.
