My best rig, bar none, that will outfish almost every other lure on a continual basis is the 4 1/2 inch berkly finess worm first in black and second choice motor oil third pumkin seed with the smallest splitshot that you can still cast with pinched right at the nose of the worm with a gamagatzu or if you must, an eagle claw featherlight worm hook. When things are really slow, pinch off the first inch of the worm, to the smooth bump on the worm. This slows the decent a lot and keeps the worm in the strike zone a lot longer.
Try this and get ready to hang on!
