Abstract
A golf club head set having the club head back side divided into four areas, including the perimeter weighted region A; the sweet spot area B located directly behind the ball striking area, two separated non-striking areas C, and the low central region D. The sweet spot area B is further divided into three distinct weight levels, and the low central region D is divided into four additional weight levels. By adding and dropping weight levels as well as by changing the thickness of the levels, the weight distribution of each club head is changed so as to control center of gravity and polar moment of inertia and provide gradated performance specific to each club head in the set.
