Getting the popcorn ready now…

so the question is, what will actually happen to you if you fall, wearing a non fall arrest device? But we need to know the other variables. Hanging from a steel chain or a bungee rope? These aren’t arbitrary details.

You are correct again sir. The force generated will determine the outcome. The materials used (variables) will determine the force generated. Design will have some impact on how you land. And of course the rope/ friction hitch/ ascender ect… how high above your tether or linesman loop you were when you fell,…. all of those are variables. They change the forces generated and how that force was applied. But if the force is great enough, the outcome is the same.

Exactly! know the rules, and know when to break them (educated decisions).

I think you get what I am saying. Operational risk management! Know your gear, know the risks involved. Always ask yourself, if I do this….. what’s the worst thing that could happen. If you are fine with that assessment, then do it. Prepare for everything and practice doing it. I salute you sir for the amount of practice and due diligence that I know you put in!

For work positioning harnesses (which by definition, is what a saddle is) you should never climb above your connection point (which would be a 1:1 fall factor) you should also keep your system tight enough so that it never generates a fall of 24” or more.

This seems reasonable for efficiency and critical for safety to me.

Wow. That video is shocking. I cannot understand these one sticking videos of guys climbing above their tethers when you consider what could happen.

Maybe they’ve evaluated the risks and decided it’s worth the chance to save the weight? Or maybe some of them saw a you tube video and decided to do it because no one ever explained what really happens if/when you fall. Regardless I pass on info, it’s up to the individual to decide what they do or how to apply information
 
If the former, that’s not what I want to do, but everyone is free to make their own decisions. But I think more likely it’s the latter, in which it case that concerns me because I think people are assuming risks they haven’t even comprehended. And I’m not looking down on those guys because very recently I was in that group before I really started reading some of the safety threads on here. That’s why I really appreciate this site. I had a close call my first experience one-sticking and it turned out okay but in hindsight I see it could’ve been way worse. Risks are fine as long as you aren’t ignorant of what you’re undertaking, that’s where I’m at.

More than you can imagine. People are modifying gear to do things and work in ways they weren't designed or tested for, they are using things out of spec, they are using ropes and materials that are not tested or approved for the application, and many cases against the manufactures recommended guidelines....

And(sorry guys) but the manufacturers and people that push these methods, and materials are being negligent by allowing customers and "followers" to assume risks they don't fully understand and haven't thoroughly evaluated for themselves...
 
Broken bones can happen depending on body position when you come to a stop.
Another result depending on the harness construction and tether attachment is the possibility of your insides getting squeezed to the outside, by any available opening, openings. It is called the circle of death if your harness is able to contracted if an outward force is applied to it. This has happen in arborist world when worker had lanyard attached to side dees and around the tree, while cutting the tree can split, slamming climber into tree and start squeezing as the split opens up.
Happy climbing after that visual!!

Extreme cases but yes that happens. More commonly is ruptured pelvis, spleens or forced trauma hernias. All of which can be fatal if you don’t get help quickly. If your back is broke and you’re still hanging in the tree, it’s not likely that help arrives quickly enough
 
I have a EWO platform/one stick build in progress and you guys have me strongly reconsidering this method!! Just kidding. I asked the OP question and I appreciate all the input. I’ll find a way to make it work safely, even if it means inch worming up the tree. But I think I will have to shift my mentality from one sticking being the most efficient climbing method to it being a packable, lightweight method that works for me.

I’m glad you brought up the topic. I’m not saying people shouldn’t one stick, I just want people to find a way to utilize their linesman rope or some other method to help reduce slack in the system. I would hate to get on here one day and see one of our beloved members hurt or deceased from a fall that could have been avoided!

^^^ great post, especially about the use of ropes not designed for the application.
