I've been choking on my sewn eyes going on 10 years, they show no signs of degradation, the line always reaches it's "expiration date" before the sewing shows any signs of wear. In pull tests at the end of the service life of my lanyards the line always breaks, eyes don't budge.

The other lanyard I'm building uses a stainless bow shackle as an alloy ring alternate so no need to sew in a steel ring.

And maybe try a quickie instead of the biners and micro pulley for the 3:1 ...I know the slick pin is loaded it don't always spin like we wish it would but maybe it will in this configuration bc it's a lighter load...
I love me some bow shackles and I like that it's not permanent so the user can customize but I think the curvature of the quickie and shackle will mix well.
I've always thought splices were ok for choking on bigger diameter wood...better if it's a long eye bc the tightest bends would be at the cinch ...

A RollClipZ will clip into any tight eye that accomodates a normal biner. They have a larger pulley than a revolver and are great for MA. I also use my two for the SCAM redirects and they are very smooth.

According to the Z, cinching rope is 100% better than choking “openable” hardware not designed for side loading. As a splicer, I see no issue choking either type of termination since they will always break higher than knots.
Furthermore, other than when you’re working for a company that adheres to or entered in a climbing competition, there is no “Z” deity constantly governing your every move. Common sense and experience are invaluable.

There’s no issue mixing steel and aluminum hardware. For instance, steel snap clipped to aluminum D ring, widely used and accepted.

I could see the benefit of the other end being setup as a double lanyard
I know. But steel wears out aluminum much quicker than steel on steel so I don't bother mixing.
I know it's accepted and I used to not care at all untill I witnessed it. So I mostly use aluminum for everything because it's lighter than steel.
I know choking is best and that the z doesn't run the show and all.
I had always heard it wasn't good to beat on splices like that and my gut feeling was as you said...that splices are strong enough and just fine to do this with.
Your input is very much appreciated.

I've put in two days of work climbs with the "Moss Lanyard" design and I'm pumped about it. I'm using it every way you can use a lanyard: MRS side D's, MRS attached to my bridge, and SRS mode. I'm now finding a bunch of different ways to use it SRS mode. Today I used every one of them.
The cool thing is zero hardware changes, every use the base lanyard configuration is the same. The exception is RADS mode where I add a micropulley. Install and removal is now super smooth, some different movements, muscle memory etc., just like any tree climbing technique you learn, things smooth out, you figure out better ways to do things.
The surprise for me today is that for positioning running a saw (on a nasty hemlock prune with wires through the tree), I was going with this constantly. Don't freak out, this is a positioning attachment. If my main rope failed I would barely move. Small diameter hemlock but tough stuff, fine for a positioning tie-in and if I was forced to hang on it, would hold me.
I'm calling it the "Two wrap standard loose cinch". For people who are nervous about a tight cinch on a sewn or spliced eye, no worries here. Very easy to move to adjust positioning without detaching, slack the lanyard, loosen up the wraps, slide it, continue. Was super useful to be able to move it without detaching/resetting it when I was limbwalking out balancing on bouncy footing doing tip prunes.
I've compiled all the SRS attachment modes to-date here, the titles should be explanatory:

Nicely done!

I updated the Moss Lanyard demo video to show the lanyard used in several modes. The cinch install is getting smoother now that I've put some hours on it. The new video is much shorter and more to the point than my initial video post.

I re-titled the thread to "Moss Cinching Lanyard prototype" to more accurately reflect what it's about.

I'm now bui;ding wht I'm calling the "Moss Woods Lanyard", it's an 80' long lanyard intended as a lightweight rec/research woods climbing "lanyard". The idea is it's a lot nicer to carry 80' as your main rope into the woods as opposed to a 150' or 200'. The lanyard could have applications in work climbing as well.
It works as a remotely settable/retrievable choked canopy anchor that can be quickly switched back and forth from SRS to MRS as needed. Instead of a captured ring sewn in just behind the end carabiner there is a double locker slic pin stainless bow shackle. The shackle allows more flexibility in configurations. The tail end is clean with a secure utility loop sewn in so that a sleeve cambium saver can be easily added in for MRS. I'll post photos and vid when ready.
