Since we'd likely only be using the rig to lower someone, I'll swap that with a steel carabiner. The redirect will be loaded somewhere around 150-175% compared to the main anchor point.
The shaft has multiple drift levels and 300' of spare rope will allow us to lower someone down to the next lower level, no matter where they are in the shaft.
I have a spare GriGri but I figured the Stop would be better since it's the device we use all the time. The way it'll be rigged, operating it will be the same as when using it to rappel. The positioning will be the only thing that's different (and that could be an important difference).

Cool! I had no idea this was possible. Please explain how to do this. Do you rig the bobbin in a "C" config? Thanks!
