#16452, "RE: best knot for leadcore line ..." In response to Reply # 0
I would think that any knot which would work with plastic or carbon coated wire should work on the leadcore.
Try the Centauri Knot (do a Google search) - this works great with plastic or carbon coated wire - or what about crimping with the smallest Momoi or Jinkai crimps and a proper crimping tool ("cup to cup" and not the usual and cheap "point to cup" tool type)?
Before you crimp, this article is a "must read": http://www.leadertec.com/tipsandtechniques/crimp_techniques.html
