Abstract
A golf club (40) has a golf club head with a large mass, relatively short club length and a moment of inertia about the Izz axis through the center of gravity of the golf club head greater than 5000 grams-centimeters squared. The golf club head (42) preferably has a volume ranging from 400 cubic centimeters to 470 cubic centimeters. The golf club head (42) preferably has a moment of inertia about the Ixx axis through the center of gravity of the golf club head greater than 3000 grams-centimeters squared. The golf club (40) preferably has an inertia ratio greater than 0.0019.
