  • Patent number: 6719648
    Abstract: The invention related to methods and a system fro precisely fitting a golfer to a selected stiffness of golf shaft and to a selected flex choice of golf shaft. Heretofore and presently, a long felt need exists for methods and means to precisely fitting a golfer to a particular golf shaft whose values of stiffness and flex choice are applicable to a player of a specific skill level in the game of golf. Present day club fitting systems and methods are very expensive, complex and do not provide methods and means for precisely fitting a golfer to the most important part of a golf club, the golf shaft and its stiffness and flex point or kick point values, to allow a player to possess accuracy and consistency in his or her golf swing/shot performance. The present inventive methods and the system invention disclosed herein satisfy this long felt need and provide accurate selection of a golf shaft for a player by providing the particular methods and analysis set forth hereinafter.
