Loomis EFP tour shafts - these shafts are legit and I would put them on par with steelfibers and Recoils. I luckily stumbled upon a set of yonex nanospeed irons with the 120g tour-x shafts for a next to nothing and have put these shafts in my ping i200's. Performance is very similar to my recoil 125 prototypes that are SS X 2, as well as very similar to x100's. If you can find them, don't shy away - these are great. I even contacted Loomis customer service asking for the specs and 1 of the owners personally got back to me with the info I requested - very cool.
If you are considering going graphite, put these on your search list, you won't be disappointed. One bonus too, like recoils, if you install logo down, all you see is a nice dark chrome finish with no graphics - sweet looking!
