Abstract
A golf club head is provided with a body that has an address position with a zero degree bounce portion on the sole and a center sole position with a multi-relief surface of the sole having a negative bounce portion. The negative bounce portion may comprise a negative 0.5 to a negative 4.0 degree surface. In one embodiment, the multi-relief surface may comprise the negative bounce portion and a cutaway portion extending to the back of the sole, which may have a depth of about 0.05 to 0.5 inch from a regular sole surface. In another embodiment, the golf club head includes a weight system to adjust the center of gravity. In one embodiment, the weight system is a tube having a weight at one end that may be inserted into the golf club head to move the center of gravity at least forward and backward within 6 mm and up and down within 6 mm. Preferably, the tube is angled downward toward the face by at least 3 degrees.
