Wilson DD6+ driver. The new DD6+ driver from Wilson features distance and speed-enhancing Energy Transfer Frame (ETF) Technology which redirects energy back off the ball to the club face. This amplifies the interaction between face and ball, increasing the moment of inertia for huge distance. With its stretched profile delivering a higher MOI, and 460 cc titanium head, the Wilson Staff Dd6+ driver builds on Wilson's proprietary ETF Technology to generate, according to Wilson, an additional 6 yards per drive. Wilson L-Pods on the back of the sole redistributes the centre of gravity low and back, producing a higher initial launch trajectory. As used by Padraig Harrington to win the Open at Carnoustie.
