Use 30-50lb leader and wire if you have to. Troll large 110mm-190mm hard bodied lures. When trolling lures, have a wide spread of different colours to suit the conditions.
Use a pilchard on a Set of 3 ganged hooks, 30-50lb leader and wire if you have to. Use a rolling swivel and a light sinker, enough to slowly float down the burley trail.
Slimy Mackerel, Garfish and live bait are also great baits. Try to avoid using wire as this can scare the fish. Only use wire if you are continuously getting bitten off.
