1. A golf club head comprising:
- a face portion including an inner zone and an intermediate zone surrounding said inner zone, said inner zone including a relatively high flexural stiffness when compared to said intermediate zone; and
a body portion connected to said face portion;
wherein said inner zone is generally elliptical in shape having a major axis and a minor axis, and wherein a ratio of said length of said major axis to said length of said minor axis is greater than about 1.5, andwherein said face portion includes a measurement zone, defined by a rectangle having the dimensions of 0.5 inch by 1.0 inch with a geometric center that coincides with a geometric center of said face portion, and wherein said measurement zone has a lowest COR that is at least 93 percent of said maximum COR.

Abstract
A metal wood golf club head adapted for attachment to a shaft, comprising of a body portion and a crown portion, each portion constructed of a different density material. Combining a high-density material in the body portion, with a low-density material in the crown portion, creates an ultra-low center of gravity relative to the geometric face center, resulting in higher launch angles and spin rate ratios. The material for the crown portion is preferably a composite. A vibration dampening gasket is disposed between the ledge and lip sections of the body and crown respectively.

11. A golf club head comprising:
-
a face portion including an inner zone having a first thickness, an intermediate zone having a second thickness surrounding said inner zone, and a perimeter zone having a third thickness; and a body portion connected to said face portion; wherein said first thickness is greater than said second thickness; and wherein said intermediate zone and said perimeter zone have an area greater than about 40 percent of a total exterior surface area and less than about 85 percent of the total exterior surface area, and wherein said face portion includes a measurement zone, defined by a rectangle having the dimensions of 0.5 inch by 1.0 inch with a geometric center that coincides with a geometric center of said face portion, and wherein said measurement zone has a lowest COR that is at least 93 percent of said maximum COR. - View Dependent Claims (12, 13, 14, 15)
