1. A golf club comprised of a golf club head, a shaft having a shaft axis coupled to the golf club head at a first end of the shaft and a grip coupled to the shaft at a second end of the shaft, wherein the golf club head comprises:
a frontal portion comprised of titanium comprising a striking face having a face center located at a forward portion of said golf club head, a crown return and a sole return;
a rear portion located aft of said striking face comprising a crown at an upper portion of said golf club head being coupled to the crown return and a sole portion on a bottom portion of said golf club head being coupled to the sole return;
an x-axis is defined as a horizontal axis tangent to said face center with a positive x direction towards a heel of said golf club head, a y-axis is a vertical axis orthogonal to said x-axis with a positive y direction towards said crown of said golf club head, and a z-axis being orthogonal to both said x-axis and said y-axis with a positive z direction extending forward,
wherein said golf club head has a moment of inertia about said y-axis (MOI-Y) passing through a center of gravity (CG) of said golf club head, said golf club head has a moment of inertia about said z-axis (MOI-Z) passing through said CG, said golf club head has a moment of inertia about said x-axis (MOI-X) passing through said CG and said golf club has a moment of inertia about the shaft axis (MOI-SA);
a first weighting member and a second weighting member, both being located near a central portion of said golf club head in a heel-to-toe orientation, substantially in line with a vertical plane containing the z-axis with said face center, the first weighting member located on the sole return and the second weighting member being located near a back edge of the golf club head;
wherein said first weighting member and said second weighting member each have a heavy side and a light side and are rotatable to move the CG along a direction parallel to the x-axis;
wherein said golf club head has a MOI-Y to MOI-Z ratio of greater than about 1.5; and
wherein said golf club head has a MOI-SA of less than 850 kg-mm2.
