Sorry to burst your bubble dude, but s914's aren't all metal. Actually, they aren't even part metal. Unless you count the screws and heel tracks. I guess
Still a killer price though.
914 LABs have metal heel base frames and worm screw heel track (ala 916,) and regular consumer single toe-wing adjustable plastic toepieces with driver AFD. Like I said, still a killer deal - and still not an all metal binding.
