short skis tend to be easier if your doing switch ups and butters and are what i perfer(like level with my eyes)...but lots of people like longer skis cause there faster and easier/more comfertable when doing big air...
I guess I go more towards the shorter skis (except pow sticks of course). I would look burly me riding long sticks though, Im 6'3 so long boarders for me would be in the 190 range.
