Partial hanging seems the easiest and least costly if it goes wrong somehow. Thinking about trying to pass out before I hang though, so I don't try to come back. I'm planning on either huffing butane/aerosol until I pass out, or putting enough pressure on my carotids to pass out before and let my weight do the rest. It's all set up and getting to it would be difficult for others, so the only thing stopping me is the fear of suffering and coming back with irreversible damage somehow.
