PRGR 01 Irons PRGR 01 Irons 4 Iron S200 423 grams Thank you for viewing. Purchased a pro-issue item, unused. Hit about 5 balls at the driving range. Feel, distance, and balance are superb. These are irons with a very high degree of perfection. I don't know of any irons better than these. It feels like a more mellow version of the good-old BS irons. Even when hitting it for the first time, it feels like a familiar club. If you are looking for irons, please try the 01 Irons. No returns or claims accepted.
