I want to climb a tree with a long trunk with little branches down low. I cannot get a throw line up.

I read in the tree climbers companion that you could use a false crotch around the trunk as an anchor.

Looking for some more info on how to set up the false crotches..

Is it safe to put body weight on?

Rope vs webbing

What knot would one use? Will be loaded and unloaded repeatedly.
