1. A golf club head comprising:
- a face component composed of a titanium alloy, the face component comprising a striking plate portion and a return portion, the striking plate portion having varying thickness, a rectangular shape, an aspect ratio greater than 1.8, and a face area ranging from 7.0 square inches to 9.0 square inches; and
an aft-body coupled to the return portion of the face component, the aft-body composed of a non-metal material having a density less than that of the first material, the aft-body comprising a crown portion, a sole portion, the sole portion having a bottom section and a ribbon section, the ribbon section being located between the crown portion and the bottom section of the sole portion;
a first weight member positioned in an aft-heel corner of the golf club head, the first weight member having a mass ranging from 5 to 30 grams, wherein the aft-heel corner is a distance Dmh from a center of gravity of the golf club head, and the distance Dmh ranges from 2.0 inches to 3.5 inches;
a second weight member positioned in an aft-toe corner of the golf club head, the second weight member having a mass ranging from 5 to 30 grams, wherein the aft-toe corner is a distance Dmt from the center of gravity of the golf club head, and the distance Dmt ranges from 2.5 inches to 3.75 inches;
wherein the golf club head has a mass ranging from 180 grams to 215 grams, a volume ranging from 420 cubic centimeters to 470 cubic centimeters, a moment of inertia, Izz, about the center of gravity of the golf club head greater than 4000 grams-centimeters squared; and
wherein the golf club head has a coefficient of restitution that ranges from 0.81 to 0.94.

Abstract
A golf club head (42) having a delta of the coefficient of restitution between a geometric face center of the face (72) and a location (806) 0.5 inch sole-ward from the face center that is less than 0.065. The golf club head (42) preferably has a volume ranging from 420 cubic centimeters to 470 cubic centimeters. The golf club head (42) preferably has a moment of inertia about the Izz axis through the center of gravity of the golf club head greater than 4000 grams-centimeters squared, and a moment of inertia about the Ixx axis through the center of gravity of the golf club head greater than 3000 grams-centimeters squared.
