    摘要： A hollow golf club is provided having an outer shell and an inner frame. The outer shell comprises one or more lightweight members. The inner frame fits within a smaller envelope and sits on the sole of the club head. One or more weights are located either on or within the inner frame to optimize the moment of inertia of the club head about both the vertical axis running through the center of gravity or geometric center of the club head, referred to as the “y-axis,” and the axis running through the center of the shaft of the golf club, referred to as the “hosel axis.” The ratio of moment of inertia of the club head about the y-axis to moment of inertia of the club head about the hosel axis is preferably 0.55. More preferably, this ratio is 0.75.

    摘要： A golf club head with an improved sweet spot, defined as a portion of the striking face that has at least 99.7% of the maximum ballspeed is disclosed herein. More specifically, the present invention discloses a golf club head with a significantly circular sweet spot that encompasses at least about 1.5% of the total striking face. A golf club head in accordance with the present invention may generally have a improved face geometry with an elliptical factor of greater than about 0.5, a beveled transition portion around the striking face of the golf club head, a variable face thickness region with decreases thickness, or even a tilted bulge and roll radius all helping improve the performance of the golf club head.

    摘要： A plurality of golf club heads wherein the difference in spin is minimized is disclosed herein. More specifically, the present invention discloses a plurality of fairway wood type golf club head with a volume of between about 110 cubic centimeters (cc) and about 250 cc, wherein the change in backspin between any two clubs within the plurality of metal wood type golf club heads is less than about 600 revolutions per minute (rpm). A plurality of golf clubs in accordance with the present invention may generally have all of its clubs maintain a center of gravity (CG) location that is less than about 8.0 mm away from a neutral axis of the golf club head regardless of the difference in loft of the specific golf club head within the plurality of golf club heads.
