And with leadcore and pendant or inline set-ups, it only takes a tiny kink and the fish could now be trailing a death rig. If you have to use leadcore, then only ever with a helicopter set-up, but my advice, is ditch the leadcore totally.
I know about inline running leads, and yes, they can work, but are they working as we think they are?
I came to the conclusion, if I want a running lead, use a run ring. If I want to fish in weed with an inline, then use a straight semi-fixed inline
