I use the muddy harness with the lone wolf rope. The rope should have a small loop on one end, with a big loop on the other, with a prussick knot in between. Slide the prussick knot all the way to the small loop and put the carabiner on the small loop. Then clip the prussick onto the carabiner. Leave the carabiner on the rope rather than on your harness. To affix to the tree, wrap the rope once around the tree and thread the carabiner end through he big loop and then attach it to your harness. When at your desired height, stand facing the tree and cinch the rope around the tree at head height. Slide the prussick knot up tight to the big loop against the tree so it is tight to keep the rope from sliding down the tree. For me, this allows just enough slack to sit down. Placement on tree relative to your height may vary. Attach the rope to the tree at the base and move it up or down while you climb or descend so you are always protected. Again, leave the carabiner on the rope so you don't have to remember how it's set up every time!! To make sure it doesn't get left in the truck, I clip it on the harness for transport and storage. Just fold the rope in half twice, and tie the whole thing in an overhand knot. I hang it over my right shoulder when walking so it doesn't get in the way of my draw when I shoot. That's how I do it!
