[email protected] Lightens Up with Ultra-Premium GBB Epic Star Line
In conjunction, a hollow-hosel design helped Callaway engineers shift more weight toward the center of the Epic Star iron heads to provide a better feel and optimize the launch conditions of each iron. In the long irons, the CG is positioned lower in the club heads to improve distance. In the short irons, the CG is positioned higher in the club heads to improve trajectory control. According to Callaway, each of the irons are close to achieving the USGA’s legal limit on COR, or coefficient of restitution, a measure of ball speed retention.
