Shiners or trout are pretty much a guaranteed LMB in my experience. Shiners are a lot less expensive than trout of course. I've dropped shiners and trout in together and watched LMB ignore the closer shiner and bee-line for the further away trout.
Most of the guides I know down in FL this time of year take customers out and use live bait. They give them the option to use artificial lures, but they tell me most opt for live bait because they want to catch fish.
