I'm gonna use them only for pipe and jumps, where should i mount the bindings?
so true. my two cents is to mount 2 back from center. I used to be on the bandwagon for center but ever since having them 2 back it seems like I have a lot more control.
If you can demo them than go and try center, back, forward, etc. and see which one YOU prefer. Just like zerospin said.
