After hearing @roadwarriortalk about the power of the rage tail menace on the Tennessee river, I bought some over the winter. For some reason I have only thrown it once until yesterday. We started fishing around 10 am with the water temp around 56. Current was moving pretty good but not as bad as in the afternoons. First fish was a dink smallmouth  that hit the rage tail hard and wouldn't let go. Then got a nicer one that bit the same way, maybe 17 inches or so. We got to a deep hole and I was just sitting down dredging the bottom and THUMP!!! Set into the slowest fish of all time but it was heavy. Up comes  nice flathead cat, turned into a handful after it saw the boat 

Never know what you'll get fishing a tailrace.
