I have never been concerned with stretch in a hanging kit because the tree limbs will bend under the weight making the line stretch negligible.

The limbs or once branches - now nubs are only for throwing the rock bag 'n line over. The trunk is what bears the weight. The branches (or what's left of branches) aren't important once the rope is up there. Go around the tree trunk. The trunk holds the weight. And a little slack ain't a bad thing the way trees sway in the wind.
