Replying to Pow skis for a small skiier. help.

hey guys so i'm 5'2" and about 115 pounds soaking wet in ski gear. i'm getting really tired of getting my ass handed to me on huge pow skis. i've ridden 185 ep's and 183 chetlers and i can handle em but not as well as i would like. i'm just too small to be on a ski that long. i'm super agressive and would only be using the ski for powder. i loved the flex of my ep's but a little stiffer would be nice. but my chetlers are way too stiff and beat the crap out of me. what would you guys reccomend? i was looking at the s7's or some 4frnts. any suggestions?
