Hey John, good to hear from you again. I tried setting some limblines for flatheads this weekend for the first time. out of 20 lines I caught 2 channels that weighed 3lbs each. I was using 9inch crappies for bait, and how those little channels got hooked I will never know. Almost all the baits were hit but no good flats got hooked. My first instinct is too get bigger hooks, bigger tougher baits and, maybe shorten up the length of the lines so they are right on the surface with no extra line to get tangled.
What do you use for bait when you are drifting for them?
