If you haven't realized it yet, there is no such thing as "the right bait/lure" until you have a fish bite it.
I have used what was supposedly "the right bait" for a certain spot and got skunked until I stuck something completely different on my line. I have had fish chase and eat my bare hook. I have had fish attack the most ungodly contraptions that have ever been cast, and ignore the most expensive lure in my tackle box.
The only thing that matters is if fish bite what you offer, and the only way to make that happen is to experiment. If you stick crappie nibbles on everything and you don't catch any fish, that is the fish telling you they don't like it. If you keep doing that and keep getting skunked, you are less smart than you could be. If you stick crappie nibbles on lures and catch fish, you are a badass fish-catching genius.
