WHY DON'T YOU LISTEN TO PEOPLE WHO HAVE ACTUALLY SKIED THEM AT MULTIPLE MOUNTS AND TO THE(FREESTYLE) COMPANY AND THEIR RIDERS?
Every park mounting thread on this site gets two main answers of "yeah man just go center cause it makes sense to me on a ski I've never used", or "go one back cause that sorta makes you closer to where the park ski was designed to be mounted bro". Go email Armada, Tyson can probably give you a few ideas of where is actually best to mount. If I remember right mounting center is mounting past center of the running surface(which would be retarded).
Andd, I can't wait to ski mine which are coming at -2.5(I think that's reco.).
