Dumb but awesome idea for people with L4 climbs. Put the final hook on ratcheting cable. Get up there first, then pause for a few seconds and release the cable so you drop straight down a foot or so and catch yourself. Make sure you can hear the audience when you video as your robot does a mid-air fall arrest. Extra points if your drive falcons are chirping mission impossible.
Don’t do this until the off-season. Please.
