Your new so I'll be helpful before ya get a steady stream of hate. First, this should be in gear talk. You'll get better responses. Second, mine are mounted at the midsole mark which is -2.5 from center. If I were to do it over again I'd probably mount at -1 of center. Not a huge difference but would prob be perfect for me. If your going to use them for all mountain and pow though I'd say midsole.
