Dyneema-friendly knots (new to dyneema)

[KC]

Knots work partially on reduction of tension thru friction(arc180s/radian PIs give greatest friction conversions)
problem: Dyneema ruling friction co-efficient approaches that of Teflon, literally almost Zer0.
>>So math will be whatever xCOF multiplier of almost Zer0 wreaking havoc against efforts in math and therefore work products (for one thing). i think adjusting friction problem directly with other materials like see in some ropes/slings works.

There is also this modified Ashley stopper that is said to slip less on Amsteel-like slippery cords: slip the regular ABoK #526 and tuck the tail through the last eye.

Not sure how effective it may be...

Not sure who "said" it was less slippery
--or, more to the point, that Ashely's Stopper
slips!?  (It's vulnerability is to pulling through.)
One can form a like knot in which the U-turned
S.Part goes around one side :: just reverse the
handedness of the OH tied around the S.Part
after it makes its U-turn.

Have you seen it holding on Amsteel-like cords under higher tensions?  If it doesn't, perhaps this may be worth trying: tie the Ashley-like stopper, but start from the Poacher's Noose (#409) instead of the Slipknot?  The '3-petal' shape and symmetry underneath the stopper are largely retained and the tying remains simple.  May even have a name somewhere.

By accident I just came across a report suggesting that the Ashley stopper indeed does not hold well in Amsteel Blue soft shackles.

One cannot be sure of the behavior :: as noted,
Ashley's is prone to capsizing/folding-tail-into-knot,
and perhaps that's what happened in this case.
(Otherwise, one must picture the material making
all those turns and just *flowing* out ?!)
