More Information about Recoil from UST Mamiya:

Recoil is a revolutionary design concept for Iron shafts that incorporates state of the art composite materials and over 30 years of golf shaft design experience.  UST Mamiya engineers have uncovered the secret to designing an iron shaft using carbon fiber that exceeds the performance of traditional steel shafts and previous carbon fiber shaft designs. See a tech interview with UST by clicking here.

For years engineers have tried to develop carbon fiber shafts that could matchup to steel, but they usually failed because of the weight constraints and lack of engineering ingenuity.  The reason for their failure was due to poor material alternatives and poor design methodologies.

The conventional graphite shaft designs were constrained due to weight.  In order to create a heavy carbon fiber shaft, engineers used heavy weight carbon fiber material which had very poor dynamic properties and would cause the shaft to feel dead and non-reactive to a golfers swing.  The most common design method for adding more weight was to increase the quantity of angle layers. This was the cause of very poor recoil properties and resulted in bad feel or dead feel, and poor playability in iron shots that resulted in poor distance, trajectory and accuracy control.

See a tech interview with UST by clicking here.

The wall construction was too thick and the material properties not favorable in producing dynamic recoil within the walls of the shaft.  Recoil iron shafts has a much thinner “angle” layers, the angle layer is the most important part of creating the recoil effect.

Recoil iron shafts has been able to maintain both the heavy weight and very active recoil properties such as hoop stiffness and active modulus properties by adding more “straight” layers and utilizing high-density material and reducing angle layers.

Features and Benefits:

  • Recoil technology allows the golfer to load and unload the shaft better on both partial and full shots, which results in better:
  • Trajectory control
  • Distance control
  • The shaft is redirecting the energy to the ball and is also transferring stored energy from the golfer to the ball.  This increases the spring effect (recoil) in the walls of the shaft for efficient energy transferred to the ball for increased velocity and greater distance.
  • Composite material construction for enhanced feel and feedback
  • Higher damping rate = better feel
  • Less stress on joints in the hands, wrists and elbows
  • Recoil™ iron shafts have a premium ION plating for a similar look to steel for easier transition from traditional steel shafts to recoil™ graphite iron shafts.

 Here is a list of all available shafts:

  • Recoil Tour Prototype 110S, 125S and 125X (0.355” tapered)
  • Recoil Tour 95R, 95S, 110S, 110X, 125S and 125X (0.355” tapered)

    These shafts are great and I have to lower my spin rate and have tighter ball.dispersion with a 100 g shaft vs. a 112 g steel shaft. Increased ball speed by 3 mph and 6 yards with a better feel than any steel shaft available. CFS is an eye opening option to better shafts, not to mention each shaft is hand crafted.

See what GolfWRX Members are saying about Mizuno’s new ST-180 driver



Mizuno has recently released a new ST-180 driver that we spotted on Tour at the 2017 RSM Classic. The company’s “wave sole” technology makes an appearance for the first time in a Mizuno driver; the design is used to push weight low and forward to reduce spin rates, and the construction contracts and expands during impact to increase energy into the golf ball. The result is a lower-spinning driver, especially for those who hit down on the golf ball, and increased ball speeds across the face.

The ST-180 drivers have a new Forged SP700 Titanium face insert that allows the faces to be made thinner — saving weight from the face while increasing ball speeds — and they feature what the company calls a “Internal Waffle Crown” that saves weight to help shift CG (center of gravity) low and forward in the head.

There’s a slew of custom shafts available for no upcharge. The stock grip is Golf Pride’s M31 360, and the drivers are selling for $399.99, available in stores now.

Below is a collection of early feedback from GolfWRX members, and make sure to join the full discussion. See more photos of the ST-180 driver here.

GolfWRX Members comment on the new Mizuno ST-180 driver

TeeGolf: I’ve seen the ST180 driver [in person] and it looks like it sits perfectly square to me. And this is coming from someone who has been playing a Titleist driver set 1-degree open for the past 3 years. It doesn’t look closed at all. 

trhode: I’ve been playing the M2 all year. In comparison at address, the ST is very closed. I had 3 customers look at it yesterday too and they all had the same reaction: closed. That being said, I did play 18 on the simulator and hit some monster drives. The head, with the Raijin shaft, seems to be just a little lower spin than my TaylorMade M2. The blue finish doesn’t bother me either. 

akjell: Hit this yesterday at the Mizuno demo day yesterday at Eagle Ridge in Gilroy, CA. Far from a hook machine but definitely a bomber. The Mizuno’s reps put me in a Mitsubishi Tensei White 70X and I could hit this this driver on a string possibly a bit better than my M1. Of the Mizuno drivers of late, this has to be the best one.

odshot68: Ordering it today. Was fit and played a round with it. Optimal launch and spin. Tensei Blue 70x at 9.5 degrees. This is definitely not left bias; first Mizzy driver ever.

nmorton: Hit this today and it’s going in the bag. Just a classic head shape that suits my eye. Been messing around with a number of drivers over the past year and haven’t singled one out. Last long term driver I had was the 850. The ST checks all of the boxes for me…looks great down by the ball, sounds solid and performs as good as any other. What really sold me was how well slight mis-hits performed. I had the 12.5 dialed down so it definitely sat open a bit. Didn’t hit the fairway but it looks sharp as well. 

evoviiiyou: Had a chance to test the driver with a couple shafts last night. The head is definitely deeper than the JPX900 and the footprint seems bigger from he set up position, very confidence inspiring like the JPX900 but a little improved. Finish and graphics are very similar to the 900 which is very nice if you like the satin Mizuno blue and I do love it just like the satin black I recently had done to my JPX driver and 3 metal. 

regiwstruk: My current gamer is a Titleist 917D3, and this is definitely replacing that. I used a JPX 900 from November 2016 through June 2017 — biggest differences are the sound and that the distance is up there with at least one of the leaders in the market. Anxious to see how it does on the course! 

Paul065: It is high launch, low spin yes but I wouldn’t say it was targeted at the average golfer. It’s basically their version of Callaway Epic Sub Zero. Rory used the Sub Zero. 

Tommyj: I went down to Carls yesterday specifically to look at the ST180. I’ve read some comments that the face looks closed. When I picked it up it was in the 10.5D position and did look slightly closed but then looked perfectly square at 9.5D and also square at 10.5D which seemed sort of odd. The shape is not for me, I had a Cobra F6 and while the ST180 footprint isn’t that big its still substantial. I like blue on drivers and the ST180 has a real quality look to it with the matte finish, having said that I’m not sure I’d want to be looking at that shade of blue all the time. The sound was an absolute killer for me, it was completely unexpected because I always associate Mizuno with being traditional and understated… ST180 launch was lower than G400 in the neutral setting, about the same when I lofted the Ping down.  ST180 was noticeably lower than D2. Longest driver of the three was G400, followed by ST180 then D2. For me the ST180 had the widest dispersion with G400 being the most accurate (by a wide margin).

Spotted: Justin Rose is testing a new TaylorMade “Hi-Toe” wedge



On Twitter today, Justin Rose posted a photo of a never-before-seen TaylorMade “Hi-Toe” 60-degree wedge. As the name suggests, it appears the toe portion is raised; we’ve seen this high-toe design from other manufacturers, and the benefits of those designs included increasing face area on open-faced shots, and shifting CG (center of gravity) to where it’s more beneficial for wedge play (likely higher for more spin and a lower flight).

The wedge is also stamped with “MG” to suggest it’s a “milled grind” wedge, much like TaylorMade’s popular wedge line that’s in stores now. There also appears to be slots behind the face, likely to also shift CG to where it’s deemed more beneficial.

Talks of a TaylorMade wedge with a high-toe design were actually started by Dustin Johnson a few weeks ago in a press conference. His full comments on that wedge are above, and you can join the discussion about the wedge in our forums.
