1. A golf club head comprising:
- a body comprising a front wall, a sole and a ribbon, the body composed of a non-metallic material;
a crown plate attached to the ribbon and front wall of the body;
a weight piece disposed within a hollow interior formed by the body and crown plate, the weight piece comprising a striking plate insert attached to and supporting the front wall of the body, a first strip extending from a heel end of the striking plate insert to a toe end of the striking plate insert, and a second strip extending from a bottom of the striking plate insert toward a rear end of the body, the weight piece composed of a high density material having a density greater than the density of the material of the body;
wherein a center of gravity of the golf club head is located less than approximately 1.7 inches from an exterior surface of the front wall;
wherein the golf club head has a robustness efficiency parameter of less than approximately 0.410;
wherein the golf club head has a volume ranging from 300 cubic centimeters to 500 cubic centimeters;
wherein the golf club head has a moment of inertial Izz about the Z-axis through the center of gravity of greater than 3000 g-cm2 and a moment of inertia Iyy about the Y-axis through the center of gravity in the range from 2000 g-cm2 to 4000 g-cm2.

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.
