Replying to Punx 182 or 173?

(accidentaly made a thread in ski-gabber, but now i'm posting it in the right forum)

Hi!

Going to buy a pair of Atomic Punx but don't know which length 173 or 182. Hope you can help me out. I'm 176 (5'9) and weigh 132 pounds.

I mostly ride park, maybe 90 % park. and 65 % kickers and 35 % rails. I have a pair of rossi scratch ghettos (167) and i like them, stiffness was nice on kickers but was hard to butter with(i'm not so good at buttering, so maybe it's because of me).

I'm leaning toward the 182s, since i have the ghettos which are shorter, so it would be nice to try out a pair of longer skis. but i'm a bit concerned about whether i will be able to butter them or not, cause i still want the skis to be playful even though they are a bit longer than what i'm used to.

soo... 173 or 182?
