Split tail as friction saver?

In that configuration,, I don't believe, the thimble has to be rated; it is the cordage that needs to be rated. The thimble is only there to improve the bend radius; and abrasion resistance, for the cordage.
I have a very similar DMM thimble design / w/ a prussic on my lanyard.
Mine does not have a rating; only a DMM stamp.

Those thimbles are rated at 40kn. I believe the reason they don't label the rating on the thimble is because they don't want any end users to confuse the 40kn thimble rating with the rating of the cord in the thimble because the 40kn is irrelevant to the applications they were designed for.

To be clear, side loading/flexing sewn tight eyes has worked very well for me, not seeing any degradation of the sewn join through the service life of both my main ropes and lanyards. I can't speak to how well spliced eyes handle flex and loading cycles.

And I think @Worthaug felt that splices eyes were all good to choke too....I respect his advice and thoughts on splices.
 
The dmm thimbles have an absurd breaking strength. You are not going to reach it by pulling on cordage that fits into the thimbles. They're barely deforming the XRR style ones when breaking dyneema. That OP or OV that is tied in a prussic and threaded into the thimble is also quite fine to hang from.
 
It's also in basket mode. If it's always going to be used in that configuration (i.e. like a ring-and-ring FS) then it will only see half the load. Loading would be different for a choked configuration, but the friction is also much higher, and loading on the hardware would still be reduced from an inline loading configuration.

Lots of stuff rated at 23kN is just to indicate that it meets minimum life support rating... actual BS could be much higher. We broke 30 pulleys from 6 OEMs (but probably made in 3 different factories, as some were identical except brand name) that were rated 20kN ~ 26kN and all of them broke over 30kN. And these were all low-end pulleys. I'd expect stuff from ISC, DMM, etc. to be even stronger. Just sayin'... without knowing how/why they performed the testing, and in what configuration, I would assume a stamped rating to be a minimum breaking strength, not an actual breaking strength number.
