I have a problem... I ordered a 7 and 8 iron mb with project x pxi, and today i tried the c-taper x and loved them! I am now ready to order the rest of my clubs and i will get them with the c-tapers. But the 7 and 8 iron i have to re-shaft and i don't want the ferrules on them to be different, is there any way of getting the outer diameter specs of the ferrules you guys use? So i don't have to 'turn' and polish the ferrules that don't fit. Or when i order my other clubs can i get a couple ferrules shipped in the box? Well thanks anyway, I'm just disappointed that I have to re-shaft 2 irons..
