I'm convinced that once you know where a fish is holding and likely looking for its food, a lure's built-in subtle motion is the key to triggering strikes. One of my go-to baits is a tube. Berkley's 1-inch Micro Power Tube is a good starting lure, but I might even try a 3-inch tube. Depending on the depth of the lie, I'll fish the lure without weight, with a jighead of the appropriate size, or subtly weighted with one or two BB-sized split shot inside the head. After inserting the split shot, I seal off the head with a plug made from an old plastic lure cut to size, supergluing it into the hollow tube.
