How big are the baitfish, what kind of baitfish are they, what color are the baitfish, what color is the water, and how big are the bass? A good all around lure is the Zoom Fluke (regular) in White Pearl or Albino. They look very lifelike in the water, and easily look like shad, minnows, or most any other baitfish. But if you have perch, bluegills, etc, I like to do what many anglers don't do and fish a tube on the dropshot, and match the color and size to the baitfish (called "matching the hatch"). For perch, generally a firetiger or and shade of yellow will do fine (this includes chartreuse). For bluegill, a smoke, smoke/blue, black/blue, or any darker shade with blue flakes also do very well. You should try the Yum Finnesse Vibra King tube as opposed to any other tube (including the regular Vibra King) because they are more slender and match the shape of baitfish better. I also think the ridges help somewhat. You may want to try a fatter tube for matching the bluegill hatch. Rig the tubes through the nose, as you would with the Fluke or most any other dropshot bait. Worms also represent more slender baitfish well too.
But if I were you, I would ditch the dropshot (they work better for cold water finnesse as opposed to hot water finnesse IMO) and go with a suspending jerkbait or a deep diving, suspending crankbait. My first choice actually, would be a 3/8 oz. spinnerbait in white or chart/white with a tandem blade combination. The reason for this is, other than they work better for cold lethargic bass (IMO) is dropshots are more suited to be fished vertically and for suspended bass. If you are casting and retrieving, a spinnerbait or jerkbait or crankbait would be your best bet. Even a jig might produce well.
In the early morning and before the sun sets, try a buzzbait parallel to the shore, fishing just fast enough to keep the blades spinning and sloshing water, with the occasional twitch. A popper will have the same effect, except you can stop retrieving the popper which is a plus.
Good Luck!
