Not any help here other to say I'm having the same problem, I've got a ton of CC which I was planning on thinning out. They catch on to hook while feeding thing real quick. Dunno, my neighbors and I have tried everything, occasionally we'll just catch one by accident on a spinner or something. Earlier in the summer, I had some luck with Shad Sides put that pooped out after several days. Now, I've basically decided to let them stay, maybe they'll control the Gizzard Shad a bit. My CC are averaging 8-10 Lbs
