Replying to Chronic vs. reno jib

I need a ski that will perform better on jumps than my invaders, but also do okay all mtn. I am 5'6" and 125 lb. I ski about 80% park and 20% groomers. from what I have heard, the both have a good amount of pop and are relativly stiff. I can get the chronics for about $200, but the jibs are over 400. I have heard good things about the jibs on this site and I wanted to know whether or not they are worth the extra money. Also, what size should I get?
