A wood-type golf club including a head comprising a body having a face, a sole, a crown, a toe and a heel and a coordinate system with an x-axis extending horizontally tangent to a center of the club face, a y-axis extending vertically from the center of the club face, and a z-axis extending horizontally through the center of the club face. A system is disposed within the body for adjusting club face angle at address comprising an element that is rotatable about a system axis that is substantially parallel to the y-axis to provide at least first and second club face angle positions at address. The element may be any shape which changes club face angle at address. The system axis may alternatively be substantially parallel to the z-axis. Or, the element may even comprise a plurality of interchangeable adjustment portions interchangeably mated with a body portion. |
