  • Publication number: 20070004528
    Abstract: A method (500) for fitting a golf club to a golfer is disclosed herein. The method includes having a golfer hit a test golf club. If the test golf club is preferred, a final golf club is formed that matches the test golf club. Preferably, the final golf club matches the following parameters of the test golf club: volume, mass, mass location, inertial values, center of gravity location, club frequency, orientation, material composition and shape. In a preferred embodiment, a test golf club with an interchangeable shaft is utilized with the method.
