Replying to New Ski's ?

Im pretty interested in getting a new ski, im currently riding a 161 dumont and a rossi sprayers 168. Im about 5'9 150 and still growing  think im too small for the dumont. I liek the sprayers but there jsut for urban. im thiniking about selling my dumonts and going to put those bindings on the sprayers. the whole point is what kind of ski  should i get if i get a new pair. im basically all in the park scene so a park realated ski would do the choice so thats were NS  comes in. What kind of sticks should i get? and bindings. and what size?
