Abstract:
1. A golf club head comprising: an outer shell; a strike plate coupled to the outer shell, the strike plate having a strike face, the outer shell and the strike face defining a club head volume; a heel/toe axis extending through a center of gravity of the club head, generally parallel to the strike face, and generally horizontal relative to a ground plane when the club head is at an address position, wherein the rotational moment of inertia about the heel/toe axis is related to the club head volume by the equation Ixx≧0.46*HV+77, where lxx is the rotational moment of inertia about the heel/toe axis in units of kg-mm a hosel axis extending axially through the hosel, wherein a horizontal distance measured between the center of gravity and the hosel axis is between about 16 mm to about 20 mm.
