A second cast part fits within the opening and is weldable thereto to form a complete integral hollow metal golf driver. The weight (mass) of the driver is distributed in order to reduce its torque and/or deflection. The mass is distributed so that it increases from the top side toward the sole side and from the heel end toward the toe. | |
