new to banana/magnetrax which board for non park but all over the place tricks

I'm trying to find a good btx/mtx board but am not familiar with these boards. The cheapest one I keep finding is the box scratcher, and then there's banana classic, and maybe some GNU ones. I guess GNU uses lib tech's stuff since they're both owned by the same company? I gathered that much.

I'm not sure what this box scratcher jib riding thing is. I sounds like it's for a very particular style.. I'm short (5'3) so a the board being short I guess is fine. My ideal is supposed to be areound 152cm right. I'm just not sure of the wide part. I do like the idea of softer flex.

Then, compare that to a classic banana, and I'm not too sure what the difference is.

I'm not a park person, I just go down slow hills, usually trying to fit in as many jumps and little tricks as I can, giong from side to side. So, it's definitely not for speed, but more in the tricks side. But it's not park either.. so not sure where that puts me. I do like more control over speed. More pop and flex over stiffness.

Can anyone teach me a thing or two about the banana boards?
