Well, i played about with some old lead core over xmas and you guessed it,
still cant find a way of using it safely, though terry hearn did an article about lead/chod and recommended using heavy mainline with l/core to reduce the overall chance of snapping of, that made me think it might be right to use heavy mainline and a weaker hooklink with the l/core.
Still think its a no go though, so im trying rig marole kevlar leader for the chod rig, its metal free apart from the quick link swivel at one end, 50lb breaking strain and thinner than lead core so any bead will slip of with ease
i will post a pic of the set up soon for you fellow anglers to give your opinion
