Summer throwing a Watermelon Candy Berkley Shakeyworm w/a 1/16oz. Tungsten was putting the hurt on them. Easily out catching my Bud throwing a 5" Watermelonseed Senko. After a few hours, much to my partners surprise, I went to the bag and switched up to a PB&J Senko. Just wanted to see how that color would perform as a comparison. My bite slowed but every fish I caught after that was much bigger on average to anything I had caught that day. That's just one time, so don't know if it would hold any sway to your theory or not, but it was true that day. Brian.
