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, two non-striking areas C, and the low central region D. The sweet spot area is further divided into three distinct weight levels, and the low central region has been divided into four additional weight levels. By adding and drooping weight levels as well as by changing the thickness of the levels, the weight distribution of each club head is changed to control center of gravity and polar movement of inertia and provide gradated performance specific to each club head.
