    摘要: A golf club head (42) having a delta of the coefficient of restitution between a geometric face center of the face (72) and a location (806) 0.5 inch sole-ward from the face center that is less than 0.065. The golf club head (42) preferably has a volume ranging from 420 cubic centimeters to 470 cubic centimeters. The golf club head (42) preferably has a moment of inertia about the Izz axis through the center of gravity of the golf club head greater than 4000 grams-centimeters squared, and a moment of inertia about the Ixx axis through the center of gravity of the golf club head greater than 3000 grams-centimeters squared.
