Abstract

The present invention is directed to custom fitting an individual with golf clubs. To accomplish such, a three-dimensional swing display may depict a golf swing prior to impact of a golf ball by a club head of a golf club. The club head may approach the golf ball at a particular attack angle. The attack angle may be defined relative to a horizontal plane that may be substantially parallel to a ground plane and intersect an optimal impact area on a golf ball. The attack angle may be a negative attack angle or a positive attack angle as defined by an angle of approach by a club head to impact the golf ball during a downswing portion of a golf swing.
