Replying to stl or surface

help me out

i am 5 10 130 lbs

i ski almost all park
cuz i cant afford my alta pass so its just my pc pass

i am either gona get 174 surfaces or 177 stls

surfaces=90 underfoot
stl=82 underfoot

do you think the stls would give me enough float for the occasional pc pow

any suggestions would be splended

btw i like a really soft ski
so anything like msps is out
'skis are like girls , the more you have the better'
