The new ST200G driver from Mizuno is one of three drivers in the ST200 series. This driver is made specifically for those golfers that have a high swing speed. This driver has a low to mid-spin range & comes with weight adjustment track to set the spin rate that you want. The face of the driver is made from a forged Sat 2041 Beta Ti which is multi-thickness & incredibly responsive at the point of impact. The structure of the head gives a solid sound when the ball strikes the face.
