<p><P>PROBLEM TO BE SOLVED: To provide a method for selectively changing the center of gravity and weighting distribution in void space in a golf club head. <P>SOLUTION: The performance of a golf club (100) can be enhanced by providing void space (102) behind a face plate (104) and above a sole portion (106), thereby reducing the club weight, and by providing a single or combinations of selectable weighting elements within volumetric coordinates of an orthonormal matrix (112) regarding the void space (102). The weighting coordinates are provided in response to ball strike flying ball analysis and physiological observation on golf-strike swinging. Modifications on ball backspin, trajectory, penetration and hook or slice can be made through the use of the definable weighting strategy. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
