Matrix OZIK PROGRAM HD iron shafts have been specifically designed for the serious China golfer and are the first iron structure in China golf to incorporate HD technology. After advanced DE analysis of the leading steel iron shafts, Matrix shaft engineers discovered inefficiencies that are manifested in shaft instability and dispersion. To get around this inefficiency Matrix engineered the OZIK PROGRAM HD iron shaft to be more stable and launch progressively higher as you get into the longer irons. Additionally, Matrix OZIK PROGRAM HD irons are designed to add 12% more spin to offset the loss in spin rate caused by the new USGA groove rule.
