Yeah good idea, let's talk realism.
First off, I think bigger bass are picky eaters (of lures), because in a normal reservoir, there's a lot of real food for them to chase and eat (or sit and eat).
You have to press the right buttons to get them to react (positively) to your bait. Realism to me is a total package; size, profile, color, action, presentation, etc. Everytime you press a wrong button, your chances of catching them goes down a little (or a lot).
It's amazing how some of the most realistic looking and amazingly swimming swimbaits do *not* have a good track record. "Certain vibrations are bad vibrations." (Yes, I stole that from Ken Huddleston's interview on STE). They are giving off some negative cues that turn fish off, for whatever reasons. I'm not a bass, so I won't know.
You have to find baits that create and sell the correct illusion. Does a jig really look like a crawfish? Does a worm look like anything you ever seen in the water? You can fish a totally wacky color, but as long as it sells the correct illusion, we're good.
