Banks is a great rainbow lake! I troll crankbaits, Roostertails. Or cast the shoreline for bass with Crankbaits and happen apon a rainbow about every 3-5th fish.
When trolling I don't use flashers. Light line. Near the shoreline.
Most of my fishing is done mid lake.
Most days it is easy to get a limit of these 16-22" eatting machines. I say eatting machines because I have caught more than one that had takin the whole crankbait in the mouth. Both sets of hooks. Talk about work!
