went down that rabbit hole a few years ago... went off on a tangent and went back to old school methods and baits, freelined prawns, beans, pulses, etc... doing summat different kick-started my catch results.... I think fish wise up to the same old rigs, same old, methods same old baits, so I tried stuff that was outta left field... worked for me...
Too many folks rock up to a water and chuck out 2 or 3 rods, (one in the margins one on the island and one in open water) with 30 baits round each one (sound familiar...?) especially on commercial waters... ask yourself what did the last angler in that swim hoof into the water...???
I ignored the well flattened bare "flier" swims and dropped into overgrown jungle swims and found fish and poked a rod into a spot with a bit of bait.... you'd be surprised what comes out
