Two schools of thought for me. Do you want the bottom jig to search the deeper parts and the upper to stay in one depth or float around some? I used an eighth on the bottom and a wooly bugger on the upper, even did a video on it near ten years ago. Using a heavy on the top and weightless on the bottom gives a completely different presentation and doesn’t need to be a hand tie. Slab uses one he calls a slab rig that has a jig up top and a Bobby garland baby shad on an Aberdeen hook on the bottom that goes everywhere when retrieved. Best I can offer is to try everything and use what works best for where you fish and the way you fish. The fish will let you know.

And for the confidence thing, leave everything else home. When the going gets tough you need to try different things not go back to what you did before. I no longer buy live bait and haven’t for many years, even learned to tie my own. It’s very cool to take some junk from your desktop and catch fish with it. Also, when the bite slows down, downsize the jig and slow down some more. That has saved the day for me many times and I catch 2 lb crappie on a #8 hook. The only thing stopping you is your preconceptions.
