Dynamic personal tether line without knots, seams, or splices (ducks for cover).

I’ve done similar splices, using an easier method, and had a couple pull tested, they lost about 17% of the mbs of the rope.  They both broke at the eye, the covers will relax was only loosely sewn down, it probably didn’t help much. Next to test is burying the cover tail a fid length to see if will strengthen the eye.

Regarding the Slyde, rope smaller than the recommended 9mm, can bind up, or bypass itself in the device.

Why though?

To answer this question: (and all its variants up thread) for more a streamlined harness when fix and following.

You spliced Kernmantle?  I'd think the only thing keeping it together would be the cover squeezing all the core strands together, which induces heeby-jeebies, rather than the core squeezing itself.

The eye is the weak link in strength and can’t be ring, or circumferencaly(?) loaded.  A tight eye makes it hard to do this.

Tight or big doesn't affect the construction of the splice, unless I'm missing something.  Good point on eye size, though I can't see a use case where the eye would be loaded off to one side, since it's girthed to the harness.  Maybe that why arborists like tight eyes that you can only just wiggle one 'biner into: it idiot-proofs it just a tiny bit more.

You’re right I was still thinking of it as a typical splice, but both halves would be pulled if ring loaded.  Arborists like tight eyes to help prevent cross loading of carabiners.

Some arborists are now using these odd-looking perfectly round 'biners.  Looks like you can load them anywhere.  I wonder if they'll catch on for TRS rigs.

There are many varieties of rings available, all need a tool to safely close, maybe a push button model will be available someday.  They’re being used as a second belay loop on RCHs.
