Abstract
A golf club head including a crown defining the top surface of the club head and including a crown portion, a crown recess region formed in the crown portion and defined by a crown ledge and a bonding wall, and a crown insert disposed at least partially within the crown recess region. The size and uniformity of the junction between the crown insert and the bonding wall may be determined by measuring the dimensions of the junction at critical points on the club head.
