Nice job. The thing that people who have not done this type of work, typically fail to appreciate, is that, after establishing the line of pull, the trickiest part is: attaching the wire rope to the tree. It is one matter to have your ground man attach a synthetic rope of up to 24mm diameter to your climbing rope, so that you can haul it up. A light wire rope requires a bit more effort/care and the wire winch rope on the Explorer would require even more effort/care.
