This class of small minnows was designed in the style of optical lures such as smelt. It is the starting point for lures that are straight and easy to spot. You can use this type of lure in a variety of applications, such as by floating it to attract fish or by agitating fish that see the lure. The best way to use the Bevy Minnow is when slow fishing with a simple retrieving motion.
As for the silhouette that corresponds to the bait, the "match the bait" technique does not depend solely on the length. You can adjust the volume by adjusting the cross-sectional area.
