A confidence-inspiring, draw-biased driver with heel focused weight location. The ST-X will appeal to players seeking a higher, right to left ball flight. With higher spin rates than its ST-Z counterpart, the ST-X, will suit moderate swing speeds, needing help producing a more extended ball flight. A new 20-gram heel biased back weight creates a deeper center of gravity for more efficient, longer drives - more often. Also available as a J-Spec option with ultra-lightweight HeLIUM NanoCore shaft for seniors and slower swing speeds. For a lot of golfers, the modern low spinning driver design preferred by tour players is a serious distance killer. The ST-X’s extra spin, slight draw bias and a higher flight will add driving distance for a surprising number of players.
