Replying to First park ski (limited choice)

Yo,

I ski in the southern alps and am confident on most pistes.  Working my first season and bored of pistes so exploring the park.  Used to skateboard so like tricks (maybe 70% rails and 30% ramps), can hit boxes and low rails, basic grinds working on my 270 outs.  Im about 5'6" 160 pounds and looking for a light weight park ski.

Limited by the shops in my resort (so I can pay in installments, cash) I have found a bunch of possible options:

Dynastar 6th Sense Serial 2011
Salomon Twenty Twelves
K2 Revivial 2011
Atomic Punx (told they are '2013' which I think is bull.  will check again tomorrow and get a pic)
Volkl Ledge 2012

Any advice?  I have searched google and here and managed to test ride the Ledges which were pretty nice.

Thanks
