The Speedline F11 driver is the fifth generation of aerodynamic technology from Adams. The F11 retains the design that cuts down on drag, allowing swing speeds to be higher, and then add the Velocity Slot to reduce drag even more while at the same time adding forgiveness. The Moment of Inertia is high, reducing errant side- or backspin due to gear effect. The Center of Gravity is low and deep to maintain high launch angles with optimum spin for increased distance. The Draw model helps you close the face through impact to promote a draw.
