Abstract
A golf club head for a metalwood includes a body having an upper surface, a central region of which is stiffened by means of two parallel ridges extending perpendicular to the club face. Also, the lower surface of the club head has two ridges to stiffen a central region of the lower surface. A cavity in the lower surface of the club head holds a weight that is collateral with respect to the ridges. The weight does not fill the cavity completely, such that a 0.030" gap borders the weight between the weight and the wall of the cavity.
