There's a story on the internet regarding Ky Lake where a bass fisherman named Bill Taylor, targets redear in the summer months. He is apparently an accomplished bass guy and won a whole bunch of tournaments on the bass tours.
He said he drop shots a light action pole in 20-30ft of water in secondary channels or the main channel where humps are present. It makes good sense, the article can be found by googling his name and bluegill/redear, it'll come up.
I read an article about Mark Davis (another top bass pro) doing the same thing.
