The G440 SFT Driver is optimized to deliver more ball speed through multiple advancements, including PING's deepest CG in a driver to date and a shallower, thinner face, while continuing to ensure the game-changing forgiveness expected from a PING driver. Each model is designed to fit a specific player type, with each head profile engineered to provide launch conditions to best match their swing. The overall system weight is lighter by 10 grams and the standard shaft length is A 1/4" longer than previous models to help golfers swing faster for higher-launching, longer drives with a pleasing, slightly muted sound.Golfers in need of slice-correction technology fit best in the G440 SFT (Straight Flight) option, which features a two-position (Draw and Draw+), adjustable 23-gram back weight. Offered in 9deg and 10.5deg lofts.Trajectory Tuning 2.0
