Coralville, IA (October 2, 2014) - Minnows? Nope. Shad? Not'a. Aquatic insects? Not even close. Go ahead fishin' geeks, take the micrometer from out of your pocket-protector and start measuring. It won't take you long to realize no two specimens in nature are exactly the same size.
Now mull over the all different movements made by each and every species. Heck, even a change in weather has underwater critters slithering and writhing with a different-dance, day-to-day, even hour-to-hour.
What's the point? Simply put, if you're not willing to experiment with lures of different sizes and actions to best match the forage swimming about, you're not going to catch as many fish.
