Replying to Skis

I need new skis next year.Heres whats up

-5' 11'
-155 pounds
-Agressive park skier
-5% powder ( only when i go out to keystone,CO)
-85% park/playing around.
-10% all mountain
-i ski east coast a lot of rails and a lot more jumps..

ive narrowed it down to 3
Rossignol Scratch Ghetto (2008)-size 174 or 181 (cant decide)
Line Chronic(2008) 176
2007 Armada ARV size 175

I really have my mind set on the ghettos..but ive saved up for a long time and im curious of which of the these skis will perform the best for what i do and how people like them
thanks
