Abstract: An exemplary golf club head having an increased amount of discretionary mass may be realized by utilizing improved drop angles, an improved average crown height, and/or articulation points. The discretionary mass may be placed low and deep in the club head to improve the location of the center of gravity as well as the inertial properties. A preferred break length may also be utilized to further improve the depth of the center of gravity. In one example, the center of gravity may be positioned to substantially align the sweet spot with the face center of the club head.

Abstract: At least three clubs of a set of golf clubs may have an average volume between about 75 cm3 and about 90 cm3. The transverse dimensions of the at least three clubs may progressively decrease from a highest volume club to a lowest volume club. At least one club of a set may include a constraining member in a cavity. A linear distance between a sweet spot and a center of gravity may progressively decrease from a lower lofted club to a higher lofted club within a set. At least one golf club of a set may include a face plate portion, and at least two golf clubs of the set may include a cup face portion. At least two clubs of a set may include a progressively increasing hosel length from a lowest lofted club to a highest lofted club. The strike face of at least one club of a set may include a bulge and a roll. A first club of a set may have a face thickness that is less than a face thickness of a second club of the set.
