Abstract
A golf club according to one or more aspects of the present invention may have a mass less than 300 g, a length greater than about 45 inches, a swing weight between D0 and D6, a head weighing less than about 200 g, a club-head volume of at least about 360 cm, a grip weighing less than about 50 g, and a shaft having a tip end, a butt end, and a shaft balance point located no more than 24 inches from the butt end. The shaft may have a torsional displacement angle greater than about 5.5° and a mass less than about 50 g. A coordinate system having x-, y-, and z-axes may have its origin at the center of gravity of the club head. The golf club head may have a moment of inertia of at least about 4500 g·cmabout the z-axis and a moment of inertia of at least about 3000 g·cmabout the y-axis.
