The weight aproach will work just fine (and it is a good solution) if there is a way to install a pulley at the top-most point (buildings, masts, towers or trees that can be climbed). Since my rope goes over a tall tree (100+ ft), directly over the canopy, excessive movement of the rope back and forth (counter-balanced by the weight), will cause a damage to the rope (and maybe the tree)due to the constant friction with the tree branches. I find "the fuse" to be a simple and inexpensive way.Andrey E.
