WYNTK:
Mizuno’s latest drivers have a face forged from an exotic titanium alloy containing vanadium, aluminum and tin mounted on a titanium body specifically constructed with carbon fiber crown and sole panels to provide the desired performance for different skill level players.
The ST-X with a carbon sole panel towards the toe and weighting towards the heel has a strong draw bias which can help those fighting a slice. The head has more depth than the ST-Z and the profile is smaller. In addition, there is J-Spec (Japan Specification) variant for those with lower swing speeds that comes with a very light 39-gram MFusion shaft. Higher swing speed golfers such as Tour players will appreciate the low-spin high-stability design of the ST-Z with its carbon sole panels toe and heel.
Mizuno’s Chris Voshall, “The ST-Z’s predecessor – the ST200 – had a reputation for being a straight-line bomber favored by our longer hitting tour players, and the ST-Z profile is no different. But with an extra year’s extra experience engineering the Forged Beta SAT2041 Ti, we were able to release a little extra ball speed and a much more satisfying experience off the clubface.”
Both models use the Wave Sole Plate behind the face to increase flex at impact for more ball speed.
