摘要:
A golf club is provided having a hollow body golf club head comprising discrete concentrations of weight or mass located away from the center of gravity or the geometric center of the club head 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, hereinafter referred to as the “y-axis,” and the axis running through the center of the shaft of the golf club, hereinafter 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.
