For bream usually around the 2-3inch plastics, had success with zman grubs in motor oil, very light jighead though or even hidden weight. Pretty slow retrieve, little hops
Storm twitching nipper are also pretty solid.
Cast near structure or under boats/pontoons.
Flathead usual 3-4inch but some people use bigger
Zman paddletails in opening night, motor oil, gold rush etc there not very fussy to be honest.
Just hop it along the bottom.
If ur heading to a tackle store im sure they can give u some tips, this is just what i use
