1. A set of golf clubs comprising a plurality of golf clubs, each club having
a selected loft angle different from that of each other club in the set; a face for striking a ball, comprising a front surface, a rear surface, a top portion and a bottom portion; and a taper angle defining the orientation of the rear surface of the face relative to the front surface of the face; wherein the maximum taper angle t in degrees for any loft angle L in degrees is determined by the relationship t=−0.0028(L2)+0.3691(L)−3.9569; and the minimum taper angle t in degrees for any loft angle L in degrees is determined by the relationship t=0.02L−0.275. |
