Got the heads for a buddy at work and built them all up to 6i length (he preferred that over 7i) and today we finally were able to go to the range.
I only hit the 6i and the 9i, but I could easily get used to these irons. They were easy to hit, felt great and flew nicely. I think he is going to get the 4 hybrid as well, I will be talking to Aaron about getting one built up.
