Double loop the 6 & 9. Remains symmetrical. Locks to itself much tighter, but remains very easy to untie. Useful? Too early to tell. Cool looking? Definitely!
It’s a good thing to experiment with variations, including doublings.
So I appreciate those who have the patience and curiosity to try things out.
This is ambiguous to me --the “doubling 6 & 9” ::
do you mean to have the S.Part turns repeated,
or have the Tails run twice through them?!
In the first case (S.Parts),
note that there is a half-doubling possible :
make a full 360deg S.Part turn (vs. usual 180 or 540)
and collar the opposing end, then tucking out,
the opposing side reciprocating.
A concern I have with such extension of the
S.Part’s path is whether it when used, e.g., in some
tow line or whatever that might see extended cyclical
loading, will the extra bit of movement available to
the S.Part spell chafing?! But perhaps in cases
–such a dropping a load on the line-- of a single
dynamic load, the bit of extra compression helps!?
