Replying to Help me set my DIN

Sorry I'm creating something else than a hate-thread or a thread on x-games..


So I just got my Whitedot Preachers mounted with the Look Pivot 18. The thing is, I do not have a clue on how high/low I should set the DIN. They range from 8 to 18. I'm not a hard charger, I will probably just use them to float around in powder. I'm doing a contest later which combines freeride and park, so there is a chance I might ski some hardpack.

I'm 6"0 and 160 lbs

Not to keen on blowing my knees out.
