According to officials at Mizuno, the most notable feature of the company’s new ST-G 220 driver is the enhanced adjustability it offers. That is a result of the latest edition of the ST family having shorter lateral weight tracks, they say, which enabled engineers at the Japanese equipment maker to employ a new center/back weight port. The combination of those three tracks and the two moveable weights, those technicians believe, lets a player transform his driver from a “low-spinning bomber to a highly playable, mid-spinning option, with fade or draw bias in both.”
“Having that little extra bit of adjustability is especially useful on tour, where we can fine-tune a player’s flight or make an adjustment for a particular tournament when the player doesn’t want the feel of a completely new driver,” said Chris Voshall, golf club engineer for Mizuno.
Recreational golfers no doubt will appreciate what that attribute will bring them as well.
According to Voshall, the weight locations of the ST-G 220 offer “a rare combination of both backspin and face/draw options.” And as is the case with previous ST Series drivers, this one also boasts Mizuno’s SAT2041 Beta Ti face, which provides more tensile strength and flexibility than traditional 6-4 Ti.
Other features of the new ST-G 220 include a 460cc clubhead that is deep-faced but shorter front-to-back as well as an optimized wave sole, to help bolster ball speed from low on the clubface.
