I have always lowered material from aloft. I have never used a port-a-wrap I or II in the air or on the ground. I have nothing to offer this thread, except that if I were to rig a port-a-wrap to a tree, of the many ways there are to do this...... cow hitch. That's with rope, though.
I would be inclined to use Boa's Loopie sling. |
