This is my first time using PING irons, and I understand why they're so popular. I think it's because they have a larger sweet spot than other manufacturers, making them easier to hit, and they've achieved a low center of gravity by placing extreme weight on the sole while perfecting the overall balance. Manufacturer: PING Model: i IRON Year: 2015 Shaft: Original steel shaft, N.S. PRO950GH Flex: R Contents: 6, 7, 8, 9, PW (5-piece set) Grip: Replaced with Perfect Pro, in good condition, still usable. There are some scratches from use, but they do not affect performance. Please consider purchasing. I am also selling on other flea market sites, so please forgive me if they sell out first.
