Love the Pit Bull's. Fit me well. Found some asian fit # OO9161-07 vs my normal # OO9127-02 Both appear to be 62-18 lens, nose bridge. Not sure on the arm. Don't flame me, I did some searches on Oakley Forum already - no difinitive answers as to whether the frames are actually different (or if it is just the removeable nose pieces) Anybody know for sure?
