A different kind of hang I heard about.
1) throw the rock bag over the branch as normal.
2) once on the ground remove the rock bag.
3) hook the caribiner into the length of cord.
4) keep the end of the cord on the ground
5) pull the cord up to the branch , so the caribiner is at the branch.
6) so now you have a big loop of cord around the branch to the ground. with a pulley at the branch.
7) hook your food bag with it's carabiner to the bottom of the cord loop.
8) pull up the cord to the branch, tie off the stop stick.
9) release the cord to the stop stick.
so there's a pulley at the branch and 1 at the food bag.
with no wt.pulling across the top of the branch.
You do need 50% more cord.
