I really like the "s". I couldnt afford or justify $400-$500 for a new TC but i can upgrade it a little at a time. It might be more expensive in the long run but not a lot to be truthful. I already have the whole drive train and no the shocks. I dont really see the need for anything else for a while running RCGT. I already have a decent amout of lead just to get to weight and the tub helps with the traction.
