so my buddies skis have the bindings at a 330 BSL and mine are at a 334 BSL. I can fit in them but will it affect anything when I'm riding, hitting rails, jumps on his skis?
most definitely will cause issues. A boot might fit in a binding (as in your case) but the forward pressure will be off, and this can lead to pre-releasing or just inconsistent releasing. Take the bindings to your local shop or mountain shop to have them check that for you.
