I've done the throwing method, the rope around the tree, and the sit down and pull. Most effective so far has been drag to the bottom and find another way out. I've got a couple very good spots that require uphill drags though. Typically I only hunt those if I'm with a friend or cousin. Still being in my lower 20's, two of us can typically get a deer out of anywhere it decides to go. That is slowly changing though. I'll keep this in mind, great post and good pictures showing how it works.
