A confidence-inspiring, draw-biased driver with heel focussed 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. If you would like to customize the shaft, grip or length, please include a request in the order comments / shipping notes section. Standard Mizuno warranty applies.
