We're working four different prototype tracks for climbing. We figured out pretty quickly that securing the rope would be the fiddly bit.
- "Keyhole" (knot)
- "Hook Drum" (loop)
- "Wringer" (plain end)
- "LevelWind" (plain end)
All but "wringer" involve pulling the rope with a winch/drum/spool. Wringer is more like a continuous intake mechanism.
