Replying to Chronic vs blend vs rocker2 92. Help me decide!!!!

I am just under 6 feet tall and a slim build 145lbs. I ski as much park as i can but only want one pair of skis and need to be able to enjoy (some) powder. My afterbang 178's must be the worst ski in the powder ever made so i am worried about the chronic because they are not much wider... Does the chronics early rise do a good enough job for a light rider like me or should i just get the blend??? And the salomon rocker2 92's just seem like a great new ski replacing the magnificent twentytwelve of last year. Give me some input please!!! Season will be here soon and i need to start prepping. Open to other skis but must have rocker tip and tail and camber underfoot. Thanks:D
