my salomon bindings need constant adjusting (then again, they are the s810s), and when i say constant i mean it.  like twice a day if i'm skiing really hard, once before i go and once at lunch cause the wings always loosen up, and i know a friend who has s912 bindings that has the same problem, but not as bad. this prompted me to go to p12s for my other skis, which work beautifully, and i'm skiing at a din lower by half a mark, and they are fucking amazing.
