I use coat hangers like some guys use brass rod to catch crappie. I cut the straight piece out of the hanger, peen both ends flat, drill a small hole in each flat and fix a small snap and gold hook to one end and a snap ring to the other end to tie my line to. I think this is what some refer to as a Kentucky rig. What ever it's called, it works great in heavy cover when fishing a minnow cause it eliminates any sideways movement from the minnow.
