carpet friendly?
 

Please define a carpet friendly track system.
Does it have to be smooth or can it have extruded (not very sharp) metal comming out for a better grip on the carpet? :confused:

Please resonpond quickly because i would like to begin a complete rebuild of our drive train, and time is of the essence.

Since the carpet is setting over the gymnasium floor, no sharp objects can be protruding out if the tracks or wheels.
