Break out and reel rip/kill the big 7-9" flutter spoons, 7" scroungers, northern style preacher jigs, or shake a 7" jerky j, armor shad, or raid fish roller along the bottom. I'd also try 4-5" versions of all of the above till I find what they want. It's basically offering the right profile very erratically, like you can't reel it fast enough before you kill it back to the bottom type erratic or slowly dancing it right on the bottom and right in front of their face like a gizzard in the final throes.
I don't think @Pat Brown is wrong about the difficulty in beating the real thing, but if you get it right, that's gonna be where the big fish are. They are not skipping out on the buffet. These are some of the easiest calories of the year for the big girls. This shad kill pattern is dominant for my water mid november thru mid december. There's also a version right after ice out till the turnover and possibly a week or two after if the warm up is fleeting.
