Great Question!!!
Spring time below 45 degrees can't beat the black marabou jig, and for 45 plus, it is the Keitech Fat 3.3 and 3.8' Sun gill swim bait. I slow crawl it along the bottom, keeping in contact with the bottom the best I can. When the fish transition onto the beds, the TRD is a killer.
Suspended Summer Bass are the worst creatures to find and catch. Limited success with a Spy Bait and Deep Jerk on windy days. Deep crank has saved a day or 2 also.
Fall, they eat most everything when you find them. Spinnerbaits and Jerkbaits in the wind are killer, when it gets flat calm the TRD and the Tube are my go to. Just starting to experiment with different drop shot presentations, but haven't had better success than with the baits mentioned above yet.
If I had to only fish 1 bait all year, it would have to be the Keitech Fat.
