Just been making up some rigs - made a scratching rig to try next time I'm out - just a one up, one down flapper - 4' of 60lb powerflex with one snood at the bottom next to the lead clip and another half way up. Hooklengths - 12" of 30lb fluorocarbon, with a luminous bead and a size 2 Kamasan b940 on each.
