17 lb x-line or another heavy fluoro main line. Slide one of the new small size korda hooklink sinkers about 4ft up the mainline, now slide a soft 4 or 5mm rubber bead onto the sinker this will act as the top bead for the chod and not move for the cast but will release easily under pressure from a fish in the event of a line break releasing the hooklink. Below the chod you can either add another korda sinker + bead and have a fixed chod or just use it running with a bead above a short weak lead link at the line end. Fish it slack and it's a safe and effective chod rig without the use of leadcore or a fused leader.
