Just bought epon af tour with diamana thump graphite stiff shaft (i'm still young, 26 years old). Start playing golf 2 years ago and carrying 11 handicapper, this blades is pretty easy to hit, great feeling and accurate. I played this morning for first time with this irons and add 10 more yards than my previous irons ( TM RAC tp mb, Touredge CNC exotics forged (both with Project X shaft)). Nice trajectory and able to stop the ball within a feet even with 6 iron. That could be because of the shaft, but i don't know exactly.
Have no idea about the Gold's blades. but, I just want to tell you if Epon AF tour is great blades and really forgiving
