Ok, im gonna try to post something that will help you, without giving you a biased opinion. Here is some of the stuff i've learned from driving several buggies, and many monster trucks. You said you wanted something bash worthy, yet nimble, and controllable like a buggy. So here are some things to think about.

Nimble??? Well, to be nimble, you need the proper suspension, steering setup, and size. For instance a shorter chassis MT would be quicker in and out of turns, and have a shorter turning radius. At the same time, you will find that the SHORT wheel base is more of a spaz to control in the air on jumps (twitchy), and is harder to pull a straight line on a straight on the power. Also think about the weight of the vehicle. A heavier truck will handle rough sections better than a lighter truck (revo excluded here). On the down side of that, the heavier truck is also more likely to BREAK on impact. So keep that in mind as well. Maybe tell us if a big block, or small block is anything of preference to you as well. Honestly though, it sounds like you just need a Traxxas Revo.
