Ray Green rated this product on 09/05/10 I've used Ping Irons for over 40 years. I had the original Ping, then Ping Eye2, then Ping Eye2+, then Ping iSi, then I switched to Pinemeadow ZR1 (Ping G10). I ordered and received my ZR1 Mark II's last week and I'm delighted I made the switch. The quality, look and feel are simply superb. These are without a doubt the best irons I've ever used. They are at least 1 club longer than the ZR1 and I'm back to hitting the length I used to hit 20 years ago. I now hit a 7 Iron 150 meters (165 yards) and the Mark II's are straighter than the the ZR1. The feel off the face is just amazing on a well hit shot. Even slightly mis-hit shots fly straighter. The Pitching Wedge and Sand Iron, although, the same specs as the ZR1, result in shots I thought I'd lost forever because of my advancing age and reduced fitness, but not so. To say I recommend these irons to anyone is a gross understatement. What I say is that if you don't get these irons you're doing yourself an injustice. Ray Green.
