I'm coming from a hand-me-down set of Ping Karsten I's. My fitter looked at them and said they were "really great irons in the 1980s" lol. I've been playing them for the last 12-13 years or so.
Alas, my 921HMs now showing as backordered until 1/30. So it looks like I'll be playing at least a few more rounds with the Pings.
