<p>A wood-type golf club head comprising toe, heel, top and sole portions, a front face bounded by the toe, heel, top and sole portions, and a rear wall bounded by the toe, heel, top and sole portions, a peripheral wall depending from the periphery of the sole portion to define a sole cavity in the sole portion, and two struts extending from a portion of the peripheral wall adjacent the front face to a portion of the peripheral wall adjacent the rear wall, the struts being in part substantially parallel to each other and in part diverging from each other and defining therebetween and in cooperation with the portion of the peripheral wall adjacent the front face, a central portion of the sole cavity, the peripheral wall being interrupted adjacent the rear wall, such that the central portion of the sole cavity is open to the rear of the club head. A set of wood-type golf clubs, in which each club in the set has strut members on the bottom of the club defining a sole cavity, and the center of gravity is placed at the optimum location for each club in the set. On the lower lofted clubs the center of gravity is positioned lower in the club, toward the sole. As the loft of the club increases, the center of gravity moves higher, toward the top portion of the club, with the center of gravity highest on the highest lofted club.</p> |
