I have come back to the game again after several years away, I have been playing for about 6 months and surprisingly my swing has returned better than I had hoped my scores have improved from the high 90s to the low 80s. My iron game use to be the best part of my game, now I seem to be shorter than everyone I play with so I started looking into newer equipment I tried the XR and XR os they seem to give me between 15-17 yards improvement and better accuracy. They seem pretty much the same is one better long term or is there something else I should be looking at ???
