I'm 6' 2" and about 225 lbs. I ski about 50% park (jumps only) and about 50% all mountain. I mostly ski in the east (Pennsylvania) and occasionally get to go out west. I would definitely say I ski at expert level. I am just getting into spins in the park, but when I ride all mountain I like to go really really fast with long wide turns.
I currently have K2 extremes in the 169 size from when I was younger. I know some companies measure ski lengths differently, not sure how K2 and Volkl measure compared to each other. I'm either going to get the Wall's in 177 or 185, not sure which. Suggestions?
