I won't get too far off topic with my response and I actually have some stuff to add to the lanyard discussion.Good comments @Phil ! This is almost as deep a philosophical tree climber question as “One-handing a top handle saw, yes or no?”.
Then there is the question that frequently comes up, “Should new climbers be allowed to see these dark arts?” (apologies to Marten Penrose, he is the only legit practitioner of tree gear dark arts!). I believe that we should not limit our discussions of new gear and technique out of fear of causing an inexperienced climber to do something dumb.
There is a difference between one handing a arborist saw and side loading a crab. A top handle saw is literally designed and balanced to be comfortably operated one handed. That's the whole point of it. The fact it has a specific hook on the back for a lanyard is just smartly added convenience. One handing a saw is still using the saw the way it was designed. It's simply cutting wood. Granted one handing is more prone to lose of control in the event of a kickback, but one handing to me is a technique that can be used when the operator has exhausted other two handed options for a cut. Side loading a carabiner is straight up not using it how it was designed.
In regards to not teaching new climbers the dark arts and not limiting our discussion on new gear...I agree we should be showing them the dark arts and not limiting discussion. (We're having a discussion right now!) They will see it at some point anyway so it's our responsibility to say, "you may see people cinch a carabiner like this but they are not designed to be used like this. Never use this for a primary lifeline" or something along those lines. I don't like seeing it fully legitimized because the branch is a big enough diameter. If it's going to be shown, it should have the surgeon general's warning presented along with it. If you get your lanyard design lined out and to market I'll be the first one proclaiming "people used to cinch carabiners then this magnificent bastard named Moss pioneered this much better, safer solution that's now available at all fine tree gear retailers".
Part of my gripe with this is that this industry struggles to be legitimate in the eyes of the public. How many times do you see companies working with no hardhats, no harnesses in the bucket, free climbing with spikes until they get to their tie in. All the time. We are a community of professionals who operate in the same market as the fly by nights. We should practice what we preach... especially with life line components.
Now on to the fun lanyard related material!
Moss you inspired me to try a couple thing that will now be a permanent addition to my climbing tool box. My lanyard has no splices. It's a poachers knot with a plastic thimble. I prefer this over a splice because I really like how it fits in my hand...and it's cheaper haha. I keep an 6mm ocean prusik on it at all times. It has never bothered me just chilling on the lanyard. My inspired options was to use a quickie just above the scaffold knot for a cinch. It worked but was roughing up my tape job and I could see it trying to tighten the eye more when I weighted the line. The second inspired option was to use the quickie through the ocean prusik. That's the winner. It's awesome. Additionally, I always use my quickie with a plastic thimble because I like the bend radius and if I drop the sucker it's easier to find. The thimble also stows perfectly in the bridge D on the treemotion Evo. The thimble will not come off the quickie unless I force it off so it's essentially one single bit of kit.
