The LST (Low Spin Technology) model is designed with a pear-shaped head and measures 445cc to deliver spin reductions of approximately 200 rpm compared to the G410 LST and 500-700 rpm versus the G425 Max. The smaller head size of the LST employs a 17-gram CG shifter with three settings (Draw, Neutral, Fade) to fit the launch conditions best suited to the golfer�s swing and desired ball flight.
