I see Pat asked all the right questions and you gave him all the right answers. Hey you have some very good LMB already. You just need to keep the population of smaller LMB in check. 7 lb CC are definitely Competing with your >20 " LMB so removing some of them should help. Smaller CC aren't as formidable predator so you could replace them for clean up crew duty. Also culling your smaller LMB should help. Its got some big fish already so you just need to maintain and improve.
