I also got the GTD irons a few months back. I still really like my GTD455 driver now shafted with a 7D and the Cross Forged design really caught my eye.
These are married to the excellent Fujikura Diamond Speeder shafts which I think from a material pov are perhaps the most technically advance iron shafts in the market. They make a great combo to these heads.
Forgiveness wise, given the X design, it's a tad more punishing then the other irons on toe and heel hits. Sweet spot strikes however... lovely.
