The variety I'm taking about is the "B" version, which is for buggy. The thing seems practically designed for baseball fields. If you want to rally through those without an "off road" car, then the tt-02 rally, or better yet, an XV-01 is probably what you are looking for. The XV-01 is one of the best chassis kits they have, and are a good value - even the non-pro version. If you want something more controllable than the TT-02, then that's the ticket, because for rough surfaces, touring cars just aren't up to the task (besides that and a few other ones more aimed at higher ride heights). It's more durable too.
