>>> The professional "Arborists" use a cloth or leather bag filled with lead shot and something called "tangle-free" line or similar to throw up in a tree so that they can pull up a supporting rope for tree trimming etc.  From what I've seen, the bag is about the size of a tear drop shaped golf ball. The idea of the shot instead of a solid weight is to make the bag less damaging if it hits your house (or window) on the way down.
