Mizuno ST-Z 230 Mens Golf Driver The ST-Z 230 Mens Golf Driver from Mizuno is a straight bias driver with great stability on off centre hits. Similar in look and character to the previous ST-Z. Boosted by the CORTECH Chamber to be faster from the face, spin less and deliver an incredible, solid sensation at impact. Mizuno’s CORTECH Chamber encases a 3 gram stainless steel weight with elastomeric TPU – taking stress from the clubface and creating an additional source of energy. Balanced Composite for neutral weight distribution Design focus is a combination of deeper CG and shorter CG distance for a balance of workability in both directions while providing higher MOI and mid/low spin. Cortech Chamber Mizuno’s CORTECH Chamber encases a dense stainless steel weight with elastomeric TPU – taking stress from the clubface and creating an additional energy source. At the same time locating weight closer to the clubface to reduce spin rates. While contributing to a more solid, powerful sensation at impact. Forged Sat 2041 Beta TI Face More resilient than commonly used 6-4 Ti, with more complex multi-thickness design – made possible by Mizuno’s CORTECH Chamber. Unified Sole Composite Carbon sole plate now a single piece to allow weight to be pushed to the extremes for overall stability. Straight Flight Bias Mass spread evenly to encourage a highly stable, straight ball flight. Modern Players Profile Pushed lower to the ground for low / mid spin performance and aligns square to open. Quick Switch Hosel 4 degrees of adjustability.

Pulled the trigger on this because of a discount.The mizuno has a slightly smaller head than the Ping and appears to lay a little open at address compared to what I'm used to. It feels slightly heavier, substantial and more solid, where the Ping felt kind of hollow and light.I had the shaft shortened a full 1" to 44.5".I love the sound, it's a solid crack with a little ring, great feedback on solid strikes.Driver technology must have come a long way in 10 years, mishits with the Mizuno are much straighter than what I'm used to.

Higher launch angle comes more natural with the Mizuno, I find the distance to be more attainable and will likely increase once I settle in and start to swing harder.I favor a draw, with the Mizuno my shot shape is arrow straight, even with a little baby fade sometimes. I think I can get back to a draw once I get used to the feel and start swinging harder.My miss is a drastic duck hook. After a few sessions with the new driver the misses are much less drastic. With my old driver I could feel the clubhead really twisting on the duck hook hits. New driver stays much more square in my hands.

As usual a Driver is only as good as the person swinging the club and how well it is fit for your game....

Good looking at set up, looks good to your eye. Swing weight is perfect. Ball flight is great.
Thank you Mizuno for coming out with a new and improved driver that fits me! I'm hitting straight shots off the tee with added distance!!! Truly enjoy playing with this and highly recommend those who's looking for a quality driver!
Nice balance and easy to use! Accurate shots are consistent. Elated I purchased this driver!
Bought this driver 2 months ago after a fitting. Absolutely amazing results. Looks great at address and ball flight is straighter with a higher launch angle than my previous Calloway driver. My friends have noticed the difference in my driving even on a slight miss hit. I went to Mizuno irons last year and was so pleased I decided to give their driver a chance. Glad I did!
Mizuno Technology & QualityGreat AdjustabilityEnjoying driving the ball with this stick!!
I was taking a whiff of the Mizuno STZ 220 stiff flex and dropped spin rate from 2900 to 2496 according to the launch machine at Dick’s sporting I bought another for my father in law from here oh man he’s going to love this thing lol
One of the most notable things about this driver is the forgiveness. I maintain consistent distance with bottom-face strikes as I do center strikes, within 10 yards. I enjoy the sound when I square it up and I'm able to play my misses much better due to the forgiveness. I'd ask anyone to give it a try before buying one of the more expensive drivers on the market.
