When the river water gets below 40 degrees the main food for the predator fish is the minnow. The Rage Tail 3.25 Swimmer fills bill in cold water tactics. Rigged on a Predator jig in either 1/8oz or 3/16oz it’s deadly when fished slow. The winter bite is light so when in doubt, SET THE HOOK! Depending on the water color and cloud cover, try several color patterns.
