Replying to Where to mount ON3P Jeffrey

I got the On3p Jeffrey 114 at a length of 186cm with look pivot bindings. I am a 3+ skier 6'2 190lbs and I was wondering where a good spot to mount these at would be. I will be doing chutes, moguls, trees, basically using it as an all mountain ski out west. I will do cliffs and natural hits with them and will also be doing tricks and occasionally landing backwards. i probably won't be in the park with them but you never know. Well anyways the reccomended mounting spot is at -4 but I could be wrong, i feel like that would be a little too far back and -2 would be better. What would change about the performance of the ski if I moved it up a little? And any reccomendations? Anyone have experience with this ski?
