my ST is 4 wheel drive, I like the handling better. I drive an HPI MT Racer the first edition.

It really all depends on where you are gonna be driving. Just bashing or plans to race in the future?

I also have a Mayhem buggy, I drive on a local clay nitro track. I want to get a Monster truck later for back yard bashing and jumping.

The buggy and ST are nice for track running but lack ground clearance for true bashing.
