Claim Text:
1. A golf club head comprising: a body defining a ball striking surface, a crown, a sole, a heel, a toe and a back; and an adjustment member operably connected to the body, and wherein the body and adjustment member are structured such that the adjustment member adjusts a first parameter associated with the body among a plurality of positions and wherein in response to the adjustment of the first parameter, a second parameter associated with the body remains constant within a predetermined tolerance, wherein the first parameter is a loft angle and the second parameter is a bulge curvature of the golf club head, wherein the bulge curvature is defined as a radius defined from a bulge curvature circle defined by the intersection of a bulge plane and the ball striking surface, wherein the bulge plane is defined as a plane parallel to a ground plane through a face center location, wherein the predetermined tolerance for the bulge curvature is approximately 3 mm from a reference bulge curvature, wherein the reference bulge curvature is measured at a reference position of the golf club head prior to the adjustment of the first parameter, and wherein the predetermined tolerance of the bulge curvature is defined such that when the first parameter is adjusted, the bulge curvature is no greater than 3 mm different than the reference bulge curvature.
