I've played around with partial suspension for .. erm.. erotic reasons… but could never find that "sweet spot" as they say to induce unconsciousness. Partial seems more humane though for ctb, even with my lack of ability to replicate. Full suspension just seems risky as all hell. I think it's pretty guaranteed you'll die because done properly there's no escape, but you very well may be in for upwards of 20 minutes of horrifying struggle to escape. If executed perfectly I think it could be quick, but in my mind and research, the only people who solidly can execute it well are legit executioners from back in the day who hung many people. "Place the knot here" has done nothing for me to be able to cut the blood flow to my brain quickly. I just feel like I'm having the air strangled from me. Great for those controlled auto erotic experiences, not so much for trying to end on a peaceful note.
