Adams Men's Golf Idea Super XTD Hybrid The Idea Super XTD Hybrid uses a new multi-material brazed construction to combine a one piece titanium crown and face with a stainless steel sole. Titanium slot in the crown combined with a stainless steel slot in the sole allowed engineers to maximize launch conditions. Slot within a slot increases the spring-like effect across the entire face increasing ball speed and forgiveness. By using Velocity Slot Technology along with optimal materials and construction techniques engineers deliver the CT of a driver while simultaneously producing one of the lowest possible centers of gravity (CG). This fantastic combination increases ball speed, increases launch angle and reduces spin rates.
