The Adams Speedline F11 Fairway Woods take innovation to the next level with the application of Velocity Slot Technology, making them the highest performing and most forgiving fairway woods available. Offered in both stainless steel and titanium models, the Speedline F11 fairway woods feature a deep, visible channel on both the crown and sole that acts as a leaf spring to increase deflection and reduce stress on the face, thereby expanding the coefficient of restitution (COR) or spring-like effect for on-center and off-center shots. The result is a dramatically easy-to-hit fairway wood with a 21 percent improvement in forgiveness across the entire face, better ball speeds and up to 12 yards of increased distance.
