Sheepgirl ring ?

[Marc LaMouche]

the Hends rings are very nicely made, smooth, black and rated 12 kg (that's probably why you haven't broken any Jo :;): ), they're great.

reading the package is another story...

i don't think that elasticity comes into play in the knots.
cher Tonio, i've no idea what you're using, but i'd maybe consider a different knot for the rings. uni / nail knots are pretty much unbreakable.
i uv/knotsense glue the leader side or dropper knots so they can't swing around through casting. a few less tangles...

salut,
marc
