(sorry for pursuing the off topic discussion, I think they are worthy notes about other scenarios)

I initially bought similar block and tackle, but the z-drag setup is more versatile and you get a longer reach for a given length of rope.

just remember, for security sake, that any knot reduces its rope strength by at least half, and that dragging against mud, rocks and vegetation is increasing the load. Also, a 500lbs block and tackle typically has a rope of much less capacity because of mechanical advantage.
