Baits I just won't use? The really expensive ones, LOL.
I've tried plenty of baits, stuff that hasn't produced for me: buzz baits, frogs, cranks & spinnerbaits (which rarely produce). I keep trying though.
Stuff I don't bother with: A-rigs/Umbrella, Carolina (anymore), and there are others.
I've said it before, I don't fish tourneys, when I hit the water I want to catch fish. What catches me the most fish and brings the most enjoyment: soft plastics, namely Senkos, Zoom Finesse, various creatures, minnows, etc.
