I have a set of G15's (6-AW). I also have the Ping Tour W Wedges (54 &60) that have the same TFC stock shaft as the G15's. The G15's are as good as any Ping irons IMO. I played them for 7 years and now they're the back up set.
I found them to be almost as long as the newer jacked up lofted irons. The only thing I had a problem with was the shaft broke at the hosel on two clubs (6 and AW). Ping replaced both. I like the fact that Ping now uses ferrules.
I'm waiting for the G700 irons to come out in March. They'll be at the PGA show next month.
