Sounds like a good plan. And if some method could be rigged that auto-magically cranked the ratcheting rope tighter as he arched up more...meaning once he goes up, he can't come back down, all the better...right? *evil grin!* Maybe by suspending a weight from the rope that gets pulled down to crank the rope tighter...kinda like an old window counter weight (which I've never used, but someone once told me how that used to work)?
