Entry level All mountain Park ski

Hey guys
I'm a skier from Italy and i'm new in the forum.
I consider myself an advanced on-piste skier...actually I ride a pair of K2 Apache Hellfire Allround Carver, and my style is classic, pretty fast with carved curves.
Used to ski almost always on piste, I'm always in search of jumps and jibs beside the track or some little walk between trees, to make the ride a little bit more thrillin' and I'm looking for new skis, better than mines to do that.

I would like to find an entry level and forgiving all mountain park ski, that would allow me besides the on-piste carving, to learn easily some basic park tricks (like jumps, landings and easy rails) and to do some off-piste.
Do you think It's better for me a full camber profile or a twin rocker one? What about stiffness?

Surfing the internet I managed to find some interesting ski within my budget (about 350$) What do you think about?
Twin Rocker:
      Atomic Panic(actually my favorites)
      Fischer Guru
      Atomic Infamous
      Head The Show
      Volkl Kink

Full Camber:
    Volkl Alley
    Salomon Threat
    Rossignol Sprayer

Any other suggestion?
I'm 5'/11" tall and I weigh about 194lb (Yes, i'm not so light :P)
Thanks in advance for helping me.

Bye
Stefano
