I've used as little as 10# on to pull the bottoms down on 10ft cedars on a dock. ditto to beagle on the limbs up. I tie the weight to the bottom of the trunk and then run fencing wire up the edge of the truck wrapping around the trunk at a few of the big branch junctions. and then up above the tree. I use wire so the jig doesn't hang up. Nylon rope will get jigs caught in them for sure.
