This is important!!~!!.. to get the system to work under load, forward and backward, you need to allow the sheet to run straight back from the car, horizontally, to a turning block before it angles up to the winch.(unless the winch is on the same plane, of course).

If you run the sheet directly to the winch from the car, that backwards force is negated and the elastic cord that helps pull it back is useless. Here's my set up:
