Replying to WHAT SKI?

Hey...I'm trying to decide which ski to buy for the 08-09 season...
I have 07 invaders right now, but they're getting small so i need new ones.
i've looked at 08 invaders, anthems, chronics, foils, thrusters, dumonts.... i don't know what i should get.

i do mainly jumps/rails, and very occasionally some powder... very occasionaly.
and i'm not doing and huge 60 foot jumps or anything. just like 25 to 35 footers

so yeah. Any suggestions (and why)?
