Replying to skis for me?

all right im 4'7' and 75 pounds, im wanna get new skis for next year but not quite sure which size or what kind, im thinking k2 juvys, line chronic minis, rossi scratch pro, armada ar3, or maybe the new full twin junior teneighty (they wont be out until next yeat though). also do you think i should something close to a 140 for size? should i go bigger or what? oh im probably a beginner to imtermediate park skier, and an advanced all mountain skier. any help would be good, thanks.
pats peak is awesome
