If they are still available, get the Sierrascope. Last I saw, they were on sale and one hell of a bargain. It'll do everything you're looking for.
However, the Parkstar is probably more of what you're looking for in a board. You can press it, hit boxes, rails and kickers and when you're done in the park, bomb down some runs. The WWW is also a great board if you're just looking to stay in the park. I've never hit a big jump with a WWW, but given it's pretty soft, I'd be a little concerned about larger jumps.
