Before you buy a Skate banana you should really have a second look at the narrower YES boards I had already mentioned. I own two of their boards and I couldn't be happier. Their camrock profile is much more versatile and stable than the Banana's rocker. The banana was a great board a few years ago when rocker was still new but not only in my opinion is it kind of outdated by now.
Had a second look at their boards too, and it seems like an awesome board. Which models do you own, and would you care to give a small review on them? And what's your view on the Asym sidecut? I don't really understand what it does and how it makes the board "better", so it would be great if you could explain it!
