Couldn't find a Bianchi thread to ask this in, but what is the difference between the Bianchi M.U.S.S S.U.S.S and G.U.S.S? And are there any other 'U.S.S's that I should know of? I've seen those 3 and could never tell any difference. I'm not a huge Bianchi fan but the frames are growing on me and I may get one. I've got a friend with a M.U.S.S and he loves it.
