I read that for flatheads over 5lbs, 97% want cutbait/fish like shad or live gills. Read this in a catfish book where they disected many flatheads from Oklahoma. I have had good luck fishing Dix river below Herrington at Rankins bottom but dont know if you can get down there anymore or not. Big channel cats and flatheads and drums. Livers and crawlers and cutbait is all I have ever used.
