Soft compression core maximizes energy transfer for faster ball speed, high launch, and low spin for more distance in long clubs Aerodynamics are optimized for lower spin to reduce drag and increase lift for more carry, higher flight, and longer distance Larger size than a standard golf ball features a higher center of gravity and higher MOI to promote better contact, more consistency, and high launch to generate more distance Callaway Compression Rating: 30 Two-piece construction Larger size still conforms to the USGA Rules of Golf
