I'm anticipating the day when the team has to facilitate a long lower (300 ish feet or more) with a long canyon rope with knot pass shinanigans not being part of the equation. This would be in the event of someone not being as confident in their ability to control their own rappel as they thought, or say they are hysterical, perhaps injured, you forgot your rope bag and throwing the rope is going to create serious problems, or something along those lines. None the less capable of landing on solid ground and getting out of the way. This would be in a self-rescue scenario when a tandem rappel set up would not be the better choice. Maybe let's imagine lowering someone down the last rappel in Heaps to create a familiar image in many people's minds. How would you set up the lower at the anchor? And those of you who have experienced such a situation, in what ways did your ability to control the descent change as you lowered, i.e. friction fluctuation Here's what I think I would do, which doesn't differ much for what I would do on any lower so, I'm curious if something could-should be added in the fact that the lower would be so lengthy. Pick it apart for flaws or ways to improve, please. 1.Stack the rope so it feeds nicely 2. Sharp edge management as needed. 3. If an ATC is around using it in standard belay (or guide mode with LSD) mode clipped into the anchor with the brake strand diverted through a separate biner. Have extra biners prepped to add more friction 4. If no ATC is round us a CRITR or Pirana inverted making sure to bring brake strand back up through a leg, horn, or biner then to the brake hands. 5. If no ATC or canyon rap device use a Munter 6. Finish it off with a friction hitch off the harness. Obviously, there are scores of reasons that a lower may not be a viable option at all, or maybe not the best one. I wish I could go out testing setups on a big cliff but no can do at the moment. Thanks for the responses.
