Replying to HELP! WHERE DO I MOUNT MY S4's.

I need to know asap. I'm 5'8, 130lbs, I'm an expert skier, and i ski around 50/50 park/all mountain (trees, bumps). I'm really looking for opinions from people who have actually OWNED this ski. I am thinking of mounting them +2.5 from boot centre, but im not really sure. I'd like to know where the ski would preform best that isn't boot centre. Also wondering how they ski all mountain with a centre mount.

Thanks NS!
