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



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.

    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.

    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.

Forum Thread of the Day: “Oldest club in the bag that you use regularly?”



Today’s Forum Thread of the Day comes from 14max who asks WRXers what’s the oldest club in the bag that they regularly use. Our members list the clubs that have been playing the longest and their reasons why – with trust often playing a significant role behind their decision.

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.

  • el_rousso: “I’m still regularly playing an old (about 25+ years old) American Open 56* wedge, the grooves on it are likely too worn to be of any use but it’s still pretty much the club I trust the most around the greens, the rest of my bag is around 2005ish (irons) or 2011ish (woods and other wedges), but I recently pulled the trigger on a driver upgrade…”
  • SecondandGoal: “Odyssey White Steel Tri-Ball SRT. Made in 2007, got it for $25 on Craigslist about 4 years ago. I’ve changed every other club in the bag at least twice since then. Going to be hard-pressed to get this out of the bag.”
  • lefty1978: “I don’t always bag this club anymore. But I have a 17° Controller driving iron from around 1999. I like it because it hits low running bullets.”
  • James the Hogan Fan: “Putter- 65ish years old, Irons from 2003, Woods from 2008, Driver from 2014, Wedges from 2016, but, one from 2002. Quite the mix I’d say.”
  • ChipNRun: “A few years ago, it was a Ping Pal putter from circa 1973. I sent Ping a photo of the clubhead for verification: they said it was legit, they just couldn’t tell what batch it came from due to primitive data markings. Until about a year ago, I played Callaway X20 Tours (2008 origin); CPreO sold me a display set in 2011. Right now, the Tour Edge XRail 7W (2012) – and sometimes its brother 4W – hold the record.”

2020 Odyssey Golf launches new Bird of Prey and Stroke Lab Ten putters



Odyssey Golf is taking Stroke Lab technology and innovation further with the release of the all-new Stroke Lab 10 putters along with the introduction of the Bird of Prey putter for 2019 and 2020.

Odyssey Stroke Lab Ten Bird of prey putters golf 2020

2020 Odyssey Bird of Prey, Stroke Lab Ten putters: The details

To say Odyssey Stroke Lab putters, along with the revolutionary mass-shifting Stroke Lab shaft, have been a success both on tour and with regular golfers would be a huge understatement. On the professional side—since their introduction at the beginning of 2019 as a prototype product, Stroke Lab putters have become the number one putter on all tours and won more professional tournaments (65 to be exact) than any other brand on all tours combined.

Now, Odyssey’s General Manager Sean Toulon and his design team are looking to advance designs again with what many would call familiar shapes but with unconventional advantages.

Odyssey Stroke lab ten putter golf 2020

First off, we have the Stroke Lab Ten. And, yes, even Sean Toulon himself is willing to admit it shares similarities to a particular arachnid-style putter that he helped originally design at another OEM many years ago. But, as a modern equipment historian, I believe it’s important to point out that as much as the “arachnid” style has been popular for quite some time.

There was another putter that predates it (released in 2005), which offered an extremely high MOI design but without the catchy name: the Ping UG-LE. The UG-LE pushed mass way back and to the corners of the head to create (at the time) the highest MOI putter on the market.

But here’s the thing: Putters and material design have come a long way since the introduction of the UG-LE and the original arachnid designs, and Odyssey is here to prove golfers just how much better with the Stroke Lab Ten.

The Stroke Lab Ten’s frame is made from ABS (Acrylonitrile Butadiene Styrene…don’t worry, I had to look it up too). Here’s a further explanation

“It is an amorphous polymer comprised of three monomers, acrylonitrile, butadiene and styrene. ABS is most commonly polymerize through the emulsification process or the expert art of combining multiple products that don’t typically combine into a single product. When the three monomers are combined, the acrylonitrile develops a polar attraction with the other two components, resulting in a tough and highly durable finished product. The different amounts of each monomer can be added to the process to further vary the finished product. The versatility of ABS plastic properties contributes largely to its popularity across several industry sectors.” (Thanks, Adreco plastics)

According to Sean Toulon, what the ABS material allows is maximum distribution of metal (heavy) mass parts to the back and extreme perimeter of the putter to blow past other putters’ MOI (Moment of Inertia: a measurement of forgiveness) but also in sound and feel.

“The sound and feel of this putter is special (thanks to the material advantage of ABS)”  Sean Toulon, Odyssey Putters General Manager

Beyond just the shape of the putter, the sole has been meticulously crafted to help the head aligned square when grounded towards the target in the playing position. Sean continues

“We got these putters to the point where ( with the alignment on top ) they have become point and shoot” 

There truly is a lot going on to make sure these putters do everything they can to help both regular golfers and touring professionals align properly and get the best possible result when putts are not hit absolutely perfect.

The Stroke Lab Advantage

Considering the MOI of these designs, you would think that the highest of high handicappers would be the target market, but in that assumption, you couldn’t be more incorrect. The designs of both the Stroke Lab Ten and the Bird of Prey were entirely driven by the tour and player desire to get every last bit of performance out of their putting games.

These putters will all come stock with the Stroke Lab shaft, which pulls mass from the shaft and redistributes it under the grip and into the head for even greater stabilization. Odyssey has proven that the shaft alone can help stroke consistency across the board, and the most notable stat is the 13 percent increase in face angle delivery at impact. This increases the make putt percentage, which when you think of a round of golf, equates to strokes saved.

If there is one more thing Odyssey knows about putters, it’s roll and inserts. With the new Stroke Lab Ten and Bird of Prey designs, the company is using an all-new Microhinge Star insert to increase the sound for better player feedback. Generally, inserts are used to decrease the sound, but in the case of the New Microhinge Star, engineers at Odyssey wanted to recreate more of the original sound and feel of the White Hot putter but with the added benefit of the Microhinge to increase forward roll.

Odyssey Stroke Lab Putter Insert roll Ten Bird of prey

This new Microhinge Star insert improves the correlation between the sound and expected distance a player will hit the ball—firmer means further. This is just another step in the design process put in place to help players of all abilities putt with greater consistency since without audible feedback, all players will have a more difficult time controlling distance.

The new Stroke Lab Ten and Bird of Prey putters will be available starting November 1. For more information check out

2020 Cobra Golf T-Rail iron hybrid set



Cobra Golf T-RAIL

New for 2020, the Cobra Golf T-Rail (Transitional Rail) super game improvement iron—the company’s first all hollow iron hybrid set.

Cobra T Rail irons fuse a hollow, hybrid shape with an iron face and topline, with the iron-hybrid design aiming to provide golfers with the perfect blend of distance, forgiveness, and accuracy.

According to the company, the hollow body construction creates a lower, deeper CG than traditional cavity-back iron designs. The lower, deeper CG aims to aid golfers in getting the ball in the air and on line easier than conventional cavity-back irons.

Speaking on the new T-Rail irons, Tom Olsavsky, VP of R&D, Cobra Golf, stated

“T-Rail irons make it easy for beginners and golfers who have lost some distance and control to gain the confidence needed to play better and have more fun. Players who need max forgiveness and are looking for more distance will be amazed at how far and straight they hit these, even being able to get them airborne from tough lies.”

The irons feature the brand’s Baffler Rails technology which seeks to provide players with more speed and stability out of every lie through its turf interaction.

The irons also contain a high-strength, forged steel face designed with E9 technology, which includes a thin pocket from heel to toe which is intended to offer maximum ball speed and forgiveness on off-center hits.

Cobra Golf T-RAIL

The new additions from Cobra arrive in a hollow, iron-hybrid construction in the 5-PW with a 4-hybrid to make a 7-piece set. The irons, which come in a black/blue colorway for men and black/lilac colorway for women, come equipped with Cobra Ultralite 50g graphite shafts (Stiff, Regular and Lite) and Cobra Lamkin REL midsize grips.

Both the Men’s and Women’s T-Rail sets will be available beginning November 1, 2019, and cost $899.
