Abstract
Ball striking devices may include: (a) a sole member; (b) at least one intermediate body member; (c) a crown member; and (d) a face member. The materials making up the sole member, the intermediate body member(s), and the crown member may be selected so that the densities of the materials generally increase as one moves in a direction from the sole member toward the crown member. Such devices may be formed as golf club heads and/or golf clubs (such as “wood-type” golf clubs and golf club heads).
