Abstract: A golf club head and golf club having a large volume, large head dimensions, and/or large face characteristics, as well as unique mass property attributes driven by relationships not often considered in conventional club head design, to achieve a resistance to squaring the club head during a golf swing that is comfortable to the novice golfer, stability during off-center impacts, and preferred launch characteristics. This is achieved in part via establishing a club head configuration and associated center of gravity location that results in a preferred magnitude of Delta1 and Delta2 values, CG angle, moments of inertia, and associated ratios, relationships, and club head mass property characteristics influenced by these variables, to account for the scale of the club head and achieve improved performance.
