Replying to Kind of skis?

Hey I have been skiing for over 10 years now, and im pretty good, i do all the tricks and shit, and i run straight down trials and do moguls really well. Since i have grown a couple inches every year and get longer skis by 10cm every year, i have only had the privledge to get 1 pair of skis A LONG time ago. Now, i think i can only grow about 2-3 inches more, and i run off 170's right now, but i do well on 160's for tricks. What size and brand should i get to last me a while?
