depends on the racestock. rossi/look racestocks have an small little mount area, but if youre skiin so hard that youre (or fear that you will) break bindings, then you should always epoxy youre bindings in. it saves a lot of grief, especially on the softer core skis
s916 on the other hand have a larger drill pattern so they really wouldnt be as prone to ripping out. but the brakes suck.
but if you havent had bindings break, look/rossi make damn good bindings
