Works great on the versatile saddle
i usually think in terms of Uninterrupted Turns 1,2,3,4,7 : single Turn, Round Turn, Double Round Turn, Coil, Fr. Prussik. Kinda a collection of others; mostly from knudeNoggin(knot head) pointing stuff out written for ages. but, who knows what the 'legal' name/ construction (if such a thing i the knot wierld) is. As pointed out the crossing would put this lacing outside of most 'definitions' of a French Prusik i think.
The 3/8 Tenex is hollow, easier to splice; then is well whipped' on ends. Also, being flat in the friction hitch, Tenex will be wider than round 3/8. But, this gives more surface contact area. For same you would need thicker round line; that would be too much leveraged around such a tight bight as the host climbing line- and probably not seat right to boot! So, the Tenex by laying flat, is also not leveraged by virtue of less leverageable 'height' on the deformed axis(outside/working part of line that is forced in tight arc; doesn't sit as high off host life line).
So, seats and grabs better; with less strength loss i think!
Now, i think the VT in action is mechanically different, the braids around the lifeline buffer the loading to the fuller stop power of the uninterrupted Turns; by bending the lifeline below the Turns. A series of 5-7 Uninterrupted Turns; would be a different kind of 'sock' grabbing at the lifeline. Likewise, a knot that is allowed to invert or alter can alter it's mechanics; and even enough to go from good to something not near equivalent!

ive used this not for years. but when i worked for bartlett it was considered unsafe and we were not supposed to use it.

That is the only exception that I an see, but that could be simply a rotation of the carabiner I think.

It is a good knot, and strong. I have never used it for climbing, but pretty much anything else. It may look somewhat unsafe, due to the way it is wrapped.. but I have never seen one fail under load.
Is this knot truly a French Prusik?
We called it the Outagamie..... why you may ask..........why not.
My second attempt at a locking brummel eye and eye splice, bought some tenex and found a samson splicing diagram and some threads on AS. Learned quite a bit after trying it for the first time. Second time it came out much more consistently tapered. I have to say it's pretty easy. I still need to lock the splice with stitching. Gonna save me some money.
