I have broken an ass load of bindings. and yea the best ones I have ever had are the look z 18 race. but I kinda broke thme too. They are super sweet though. they never prerelease, but do come off those few rare times that I want them too. the only bad thing is that the heal piece can easilly ass rape you when you crash.... not a pleasant experiance at all.
My second choice is definitely the salomon 900. but not the new ones. they have seriously gone down hill in the last 3 years. they are trying to make them all light and adding all these extra safety shit on there. If you can get a pair from 3 to 4 years ago, they are gold. or get the pro race binding - if you can fnd it. it is heavy, but super good. salomons do prerelease from time to time though.... but they are still my second favourite. but look are the best I have found.
