Abstract
Wood-type golf clubs and/or golf club heads include: (a) a golf club head base member including a face member having a ball striking face; and (b) a polymeric body member engaged with the golf club head base member, wherein the polymeric body member is formed via a rotational molding process (or other centrifugal force inducing molding process) and/or engaged with the golf club head base member via a rotational molding process (or other centrifugal force inducing molding process). The polymeric body member forms at least a portion of a crown member of the club head in some structures.
