9. The golf club head according to claim 8 wherein the ribbon section of the aft-body is substantially vertical.
10. The golf club head according to claim 1 wherein the at least one weight member has a density ranging from 7 grams per cubic centimeters to 12 grams per cubic centimeters.
11. The golf club head according to claim 1 wherein each of the plurality of aft-bodies has a mass substantially equal to that of the other aft-bodies.
12. The golf club head according to claim 1 wherein the aft-body attached to the face component results in the golf club head having a heel bias center of gravity location.
13. The golf club head according to claim 1 wherein the aft-body attached to the face component results in the golf club head having a neutral bias center of gravity location.
14. The golf club head according to claim 1 wherein the aft-body attached to the face component results in the golf club head having a toe bias center of gravity location.
15. The golf club head according to claim 1 wherein striking plate portion of the face component has a thickness ranging from 0.010 inch to 0.250 inch and the return portion has a thickness ranging from 0.010 inch to 0.250 inch.
16. The golf club head according to claim 15 wherein the striking plate portion has concentric regions of varying thickness with the thickest region in about the center.
17. The golf club head according to claim 1 wherein the golf club head has a moment of inertia, Izz, greater than 3000 g-cm 2 and a moment of inertia, Iyy, greater than 2000 g-cm 2 , wherein the moments of inertia are defined by the vertical axis Z through the center of gravity of the golf club head, a horizontal axis Y through the center of gravity of the golf club head and substantially parallel to the striking plate portion, and a forward to rearward axis X through the center of gravity of the golf club head, the X-axis, the Y-axis and the Z-axis being orthogonal to each other.
18. A golf club head having a center of gravity location suited for a particular golfer, the golf club head comprising:
a face component composed of a first material, the face component including a striking plate portion and a return portion, the return portion extending a distance ranging from 0.25 inch to 1.5 inches from a perimeter of the striking plate portion; and
an aft-body coupled to the return portion of the face component, the aft-body being selected from a plurality of aft-bodies, each of the aft-bodies being composed of a second material having a density less than that of the first material, each aft-body including at least one weight member,
wherein the plurality of aft-bodies includes a first aft-body to provide the golf club head with a neutral bias center of gravity location, a second aft-body to provide the golf club head with a toe bias center of gravity location, and a third aft-body to provide the golf club head with a heel bias center of gravity location, and
