The X model is designed for Tour and amateurs seeking a fast, low spin head that offers high launch and forgiveness. NEW FUTUREFIT33 ADJUSTABLE HOSEL The FutureFit33 system features 33 unique loft & lie settings to unlock more customization options than ever before. For the first time, loft & lie can be adjusted +/- 2 degrees independently from each other, allowing for more fine-tuned fitting customization. The innovative SMARTPAD design enables the face angle to remain square regardless of the setting. MORE EXTREME AERO DESIGN An improved aero shape features a higher crown peak, and a more streamlined shape with smoother curvatures for further drag reduction and maximized speed. TOUR INSPIRED SHAPING A refined clubhead shape features an elevated look at address that promotes workability and control with added forgiveness. NEW INTERNAL ADAPTIVE WEIGHTING SYSTEM A re-engineered PWR-BRIDGE weight (in the 9.0 driver) is shaped with a slight curvature to position the CG lower and more forward to reduce spin for increased speed creation. LARGER H.O.T. FACE INSERT A larger forged face insert with H.O.T. face technology delivers improved face flex for more robust distance and ball speeds. BLEND OF FORGIVENESS & SPIN CONTROL A back weight is accompanied by a second forward weight, allowing for additional spin-tuning control. Speed/Distance Adjustment tool is NOT included
