Ever since I made the change from the Titleist AP2 platform I've been playing the Srixon 765 and sometimes 965 in the short irons. Recently I got a set of the ZX7 with the KBS TGI 100 in them. This will be quite the transition I believe coming from the KBS $Taper 125. I will keep posted in how this goes but so far the clubs look amazing and the shafts feel extremely smooth and very stable.
