Wind the rig so the float dots down with a bulk and one or two droppers. Elastic matches the fish. Plumbing is not optional. A puller kit for anything that can break light elastic.
You can buy ready-tied rigs to learn. Then wind your own so the depth marks match your kits.
Components
Pole float 4x10–4x18, bulk, droppers, 0.12–0.17mm, hooklength 0.10–0.15mm, size 16–20, elastic 4–14.
How to tie it
Connector to mainline, float, bulk, droppers, loop to hooklength. Plumb. Mark the kit. Pot, then fish.
Common mistakes
Not plumbing. Elastic that doesn't match. A waggler float jammed on a pole rig. Feeding a different distance to the float.
