I wonder how long your tree saver strap / webbing is.
I first had 50" then 2 meters and by now I just stepped up to 3 meters (might cut it back to 2.5 meters, depending how I go).
Do you just have small trees in the US?
I had now several times the problem that I couldn't get the 50" strap around the tree, our old gum trees are big and the first branch to high up to reach!
What lenght do you use?
