I had a set of TourStage irons w. Recoil 110's in stiff and that rig was the nicest feeling....BUT.....i had lots of trouble flighting the ball down. I really dont think it was the iron heads. Perhaps this is why you dont see them on tour much if at all (not that I am equating myself w. a tour player). I even had the irons bent 2 strong because the rig felt so sweet and that still didnt do the trick. It wasnt that the flight was super high on stock shots...it was when I wanted to flight the ball down that these Recoils gave me fits..i had to make huge adjustments compared any other shafts i;ve hit and couldnt reliably flight the ball like I wanted to....they just wanted to go high. I have lots of experiences w. Project X flighted and didnt have this problem and my current 2 sets of irons are fitted with s300SL's w. pro soft inserts and Graphic Design GAT95, both of which I have good control of the flight over. The prosoft inserts cured some chronic wrist tendinitis I was enduring so served the purpose of graphite on the cheap.
