There is special cord designed to not get stuck in trees. It is called "arborist throw line". It really works, I use it for bear bagging on backpacking trips. You can get the line, a throw weight, and a storage bag as a throw kit.

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.
