Replying to Help finding a one ski quiver!!

I want to get in the powder more but i don't want a full on fatty. What are some choices that would be good for me?
My park skis are 160 with full camber. I don't know my height right now but for reference the skis go to the middle of my nose.
I weigh about 120 and i don't ski too hard.
I want this ski to do everything. Park, groomers, crud, powder, small bc booters and everything in between.
What i want in the ski is: lots of rocker tip and tail with a medium flex. Lightweight and something from 100 to 115mm waist. I am looking at last years on3p jeffreys but they are pretty expensive still. I dont want to be spending too much money. Help please!
