I have to say that you are right for the most part but also dead wrong. I've seen too many fish chase and nail something. Chum can actually be quite aggressive. That's why I asked the question in the first place - because I've experienced how fun it can be when they are aggressively biting.

So on the corkie thing you use a slow retrieve - are you fishing close to the bottom or just using a little weight and trying to keep it up say in the top 3' beneath the surface?
