I use real worms and I make most of my own harnesses.
Got my blades from Lure Making .com, Beads I got from the Dollar store years ago, can find them now
Was using 1 1/2 oz. snap weight, I let out 50' first then put my snap on then let out another 150', make sure you let out very slowly because you'll get snagged.
Lots think it's the lure or colour, white shows up big time. plus a harness stays put. not like a lure "spoon or body bait swinging back and forth.
You watch a under water video and see a fish miss the bait moving, worm harness blade spins the hook stays still, but that is my theory anyway.
Ever think so many coloured spoons and it's the underside is what they see chrome flash. or a white underside. People get a tracked to colours, again my theory.
But I have been wrong lots of times.
