What snowboard should I buy?

I want a new snowboard around 150cm. I like Gnu and LibTech because they have the magne traction and the reverse camber. I love the feeling of these boards but I'm not sure which one to buy. I would like a flexible board because I am pretty light so I want some spring to it. I like doing jumps, powder, carving, so pretty much just a good all around board. I am willing to spend quite a bit, but no more than $500. Thank you for answering.
