From mid-June on (or after the topwater bite ends) I put out a light, go to sleep for a couple hours and then snag bait fish and drop them about two feet off the bottom. I also jig Mann-o-Lures and imitations. I don't troll anything in the dark. I troll spinner/worm from first light until I stop getting bit. I find the thermocline and troll along the rocky banks and around islands where there is a "feeding shelf" at the depth where the thermocline intersects the bottom. Same with deep redfins, wally divers, deep thundersticks, reef runners and deep husky jerks. Redfins and reef runners are my favorites.
