i have to admit that my biggest catfish by rod n reel (8.5lb channel) was caught while bass fishing with a crankbait. It wasn't a crawdad imitation, but it was brown with gold glitter, so it was similar. And, my only flathead by rod n reel was caught while bass fishing also. I was pitching a brush-hog (white) at docks. I think most of them are just reaction strikes though.
