Publication number: 20140302946Abstract: 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.Type: ApplicationFiled: May 6, 2014Publication date: October 9, 2014Applicant: SRI SPORTS LIMITEDInventors: John J.
