So I believe that this would work fine when the middle person is being suspended, but I don’t think the physics work out when you’re dangling someone at the end.

The person at the other end would need to be working their ass off to keep them from falling, the person in the middle would just be a fulcrum basically and wouldn’t be able to help much at all as the log spun in their hands.

It would probably work with more than three people. I think it’s dicey with three, I think that if they all hold on they would all be going in the hole.
