I have seen a pair of Line Prophet 98 2011/2012 forsale in the 174 size. I am 5' 11" tall around 185 lbs. Is this too short for me? I am an upper Intermediate skier.
I would say you should be on AT LEAST the next size up.
I ride the 174s at 5'10" / 150lbs. It's the perfect size for me, so you might be comfortable on them for a season and wanting more shortly after. Cheers.
That is what I was thinking as well.
