I know what you mean about the lack of larger fish. Usually if you catch 10 at least 1 is decent. This year it is 15 before a good one. Using 14" plus as a reasonable size, here is what has worked for me.
3" green pumpkin power tube on a 1/16 weedless jighead, flame tiger rooster, Zara Puppy, Mean Green Crappie Crank, green/gold Crappie Crank and a 2"green twin tail grub rigged as a beetle spin.
As the water temp starts to drop the larger fish should become more active.
