I'm a very short person standing at a massive 5'2" and 110 pounds. But that's not what I need help with. Finding pow skis is what I need help with. So far I've narrowed it down to the K2 Seths (169) and the Line Elizabeths (172). I normally ride a 160 but I figure that since they're for powder that they'll be easier to push around at the longer length. Will these be "too much" of a ski for me? Am I doomed to ride "skinny" skis forever? Any other brands/skis I should be looking at?
