so it stretched, didn't really work,
, in spite of pulling it, short, in the installation of the cord, and wound up on the nipple,
until thread ran out. ?

you compensated for it not functioning by doing what you may have , without it
..de tensioning the spokes opposing the missing one?

OTOH, Bringing a proper spare spoke .. replacement takes more time .. once.
one will have to replace that fiber thing with a real spoke , next..

Premeditated alternate choice, I built touring wheels, with abundant spokes in them,
myself. spares in the wheel., the spoke break got the spot truing,
and I rode for a few days more , until I got around to doing the replacement

best hub design unfortunately few hubs [none current]
use the double keyhole drilling to pass the hook head thru the flange ,
then tension pulls in a narrow slot , either side of a larger hole

....with the gears in place..

I see all sorts of race wheels under tourists , touring the coast, come thru the shop

yesterday a Korean Guy lucked out, we had a black bladed spoke that fit.
