This is a tough answer as the baits change from the beginning to middle and then end of the year. Heck the bait of choice changes based on the weather. Overall I would say a 4-5mm tungsten and waxie is bait of choice during the hardwater season.
I’d say hard to beat a 4MM Tungsten jig or even a 3MM when the bite is tough. I prefer a larva over a wax worm, they last much longer on the hook. Although on Crappies somedays tipped with a plastic will out fish live bait. Depends on the aggressiveness of the fish
