Abstract

Wood-type golf club heads include: (a) a ball striking face; (b) a club head body engaged or integrally formed with the ball striking face, wherein the club head body includes a sole portion, wherein the sole portion includes a slot or rail defined therein; and (c) a weight member at least partially located within the slot or rail. The weight member may be mounted at plural positions along the slot or rail (optionally at least partially within a weight cartridge member provided with the club head body). The weight member also may be movably engaged with the weight cartridge member, slot, rail, and/or other portion of the club head body. Golf clubs including these club heads and methods of making and using such golf clubs and golf club heads also are described.
