The cougar 2 was my first car, the "team" version was the mutts nuts.
TC`s went back to belts because of torque steer, this is not some thing we suffer from in off road due to the size and weight of the wheels. Also a shaft car was crap in low grip situations especially from a standing start, as the motor effectively tries to flip the car it lifts one side slightly and loses grip. In the dry though you have a different story though, belts get shafted. We dont seem to suffer from this though in off road.
Shaft is the future, less maintenance, more punch and no pingage
