Within the Adams Speedline F11 Driver the distance of aerodynamics meets an easy-to-hit clubface in the new, larger foot print of the fifth generation . The addition of Velocity Slot Technology (three visible channels precisely located on the sole and crown to keep the airflow attached to the club head even longer) creates 35 percent less drag and increases club head speed, making the Speedline F11 driver faster than ever. The result is over six more yards of carry distance, confidence-inspiring shaping of an expanded hitting area and a higher moment of inertia (MOI) that creates higher ball speed and forgiveness, even on off-center hits. Other design improvements include a lower and deeper center of gravity that produces a higher launch angle with a lower spin rate.
