Luca, excellent diagram of the wrong orientation!
--you need the ends to run the opposite direction
(so that the coils are pulled on like for the
rolling
hitch and not like
ProhGrip (Blake's hitch)).
It's good that you showed the
clove orientation
rather than the
cow for the
Prusik-like gripper.

. [ but then Dan tries Luca's "wrong" way :
]
Okay, maybe I like your orientation better --the loading
of the knot pulls coils together. (I'd half-wittedly thought
that loading against each other would defeat gripping
--as the extending *away* coil can push against the
other in a
Prusik hitch--, but these just get better.)
!!
Cutting down the bulk with Occam's Razor, I find that
the
Gleipnir-like versions using the (mere)
clove hitch--in both orientations as we're discussing above--
work quite well (in some nylon, fine-braided venetian-blinds
cord (2mm?), tied around 3"dia PVC pipe --so, slick and able
to transfer force around pretty easily).
I.p., they grip much more tenaciously than the
constrictor(which loosens by putting pressure on the tails pretty easily).
