About all I use for channels and blues is shad, fresh caught shad. I do use shrimp when the channels are spawning, and live perch for channels and flatheads on limblines.
I heard about how great Sonny's was a few years ago, and went halves on a case with a young fella that was telling me how good it was. I still have my half...well I did give away a jar, and did use about a half jar, but all I caught was little channels, and I mean little ones. I don't think I ever caught caught a keeper with the stuff.
I would gladly send you the stuff to get it out of my garage, cheap. If you're interested send me a PM, and we can work out the details.
I'll never use the stuff.
