i'm not pat but i have run one ways on carpet. A shaft,(or in the case of belt cars, layshaft) one way, can be used sometimes. In the case of the TC3, it tends to help the car roll thru the corners better without upsetting the balance too much. Depends on the car though. The one way diff usually is too much though. The difference between on and off power steering can be pretty violent, and the car tends to be really unforgiving off of the corner. In other words if you get on the power with the wheels still turned you go right into the board. And they feel really inconsistent and squirrelly. In other words turn all the one ways bad habits on rubber tires up to 11.
