Great question Speck. Always been my belief that there were multiple hatches of shad fry, know i've seen some smallish ones just recently so maybe they have a choice. Talked to one of the more well known names in CM events and his opinion, assuming he told me the truth , is that when the fish are in a more neutral feeding mode they might opt for a small bait quicker than a large one. He related it to people when they have eaten recently or aren't hungry but might take a snack if offered. Assuming that is true, I'm taking Twinkies with me next trip.
