I played true blades for many years first Wilson FG17 and then FG49.
Up until recently I played with and still have a set of Titleist 695MBs 2 iron thru to PW.
My view is if you are playing often and practising regularly, then blades are the thing. They give far more feedback than the "forgiving" irons and you learn how to strike the ball better because of it.
I have moved to AP2s now, mainly because I know I ain't going to be playing as regular, (other commitments have arisen which sadly keep me away from the game I love). But I'm not getting shut of them - I live in hope that one day I will be out on the course and the practice ground every minute god sends again.
It is also the fact that when looking down at a beautifully engineered classic forged blade, you get inspired to want to play them. Some clubs such as a various models in the Callaway and Ping range just do not do anything for me at all. They might be forgiving but to me they just look like gobs of metal stuck to the end of a stick!
