Some have expressed an interest in hearing about the 1/6 side. Well. How about throwing a track on 325 pounds of kitty. You cant pick it up. At least I cant. You may be able to back into it and get it to travel back on. If you decide to go with the pull a pin out (at least on mine) it means cutting a retaining pin. Pulling out a track pin. That usually mean driving it out from the other side. Still having to lift up one side to align the track. Putting the pin back in, washer, and another retaining pin. Hopefully not in mud. My Tiger is much like the real ones as you have to be very careful about backing up. Good way to toss a track.
