Replying to Help me decide

So, I'm going to get new skis. I am about 5' 11" 155 lbs. My current skis are 158cm (Yes I know they are way to small). I was going to get around 170cm - 175cm skis. I ski about 70% rails and 30% jumps. I ski in Minnesota except for the occasional trip out west. I ski 100% camber skis right now. Should I try rockered skis or stick with camber. I want a good park ski under 350 dollars. I have found one deal. Armada T-Halls 171cm for $313.99. Are these skis not for me or what? I was wondering if their are any other ski deals in my area of skiing and price range.
