ABSTRACT:
A golf club head (20) having optimized inertial properties and center of gravity is disclosed. The golf club head (20) preferably has a volume between 300 cubic centimeters and 500 cubic centimeters. The golf club head (20) has a center of gravity located less than 1.7 inches from an exterior surface of a front wall (30). The positioning of the center of gravity of the golf club head (20) and the optimized inertial properties provide the golf club with greater ball spin robustness and better performance.
