    摘要： 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 cm3, 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·cm2 about the z-axis and a moment of inertia of at least about 3000 g·cm2 about the y-axis.

    摘要： A golf club head includes a striking face having a face center, a bottom portion, a top portion including an exterior surface, a hosel including an imaginary vertical hosel plane, a forwardmost point, and a rearwardmost point. In an imaginary vertical plane perpendicular to the hosel plane and passing through the face center, the exterior surface includes a path having a first point and a second point rearward of the first point. An imaginary infinite straight line passes through the first point and the second point, but does not penetrate the exterior surface. A segment of the imaginary straight line is delimited by the first point and the second point. A maximum distance between the segment and the exterior surface of the top portion is no greater than 0.70 mm and a distance between the first point and the second point is no less than 22 mm.
