I was after little guys, hornyhead chubs. I used a worm on an aberdeen #6 hook. No bobber. No sinkers. I just cast into the river and let the worm drift down. There's a lot of chubs in the river (plus rock bass, little perch, and little bluegill). I also saw a big carp and caught it, too (on ultralight gear no less).
