are you looking for a ski that crushes on pow days, that can also manage a few park laps? or you have a park ski, and you just want a fatty to slay the deep?
at your weight you dont have to go over 110 to get perfect floatation (physically, 115 underfoot floats a 200lb man above or just 2inches under the surface, which is optimal), and under 110 is going to be much better for park.
if your looking for a fatty, get a 175 VJJ and itll handle the deepest days. If you want something that will shred pow well, but also be good in the park, get a 171 on3p jeffrey. its a dude ski, and i wouldnt recommend any other on3p for a chick, but the jeffrey is definately doable at that length.
