boarder boy

Looking at the GNU and Lib Tech 2011 lines for my new deck.
I've posted similar questions before regarding the riders choice and the TRS however I think now I would like a more aggressive freestyle board geared towards freeride more so than park. I'm growing in confidence and hitting more jumps also.
My current GNU Carbon Credit 150 feels a little unstable when i'm gunning it.
Now i'm looking at the:
GNU Danny Kass 153
Lib Tech Jamie Lynn 151
Lib Tech T Rice in 153
while keeping the riders choice in the back of my mind.

The specs for these boards are pretty similar in a lot of respects but the small differences confuse me.

I'm 55kg, 165cm, size 7 boot, looking at ride spi bindings

If someone could put some daylight between these boards for me that would be really helpful!

Cheers,
Tim.
