Mike what flies were you using on Brookville tail water? I assume streamers but you never mentioned, I know you were swinging, did you do any nymphing? Just call me curious, I have had good luck on walleye with leach patterns, tied the same as a bugger but instead of marabou for tail I used peacock herl about two shank lengths long about 6-8, and a few 6-8 rubber legs mixed with the herl. They have a slower action than the traditional bugger patterns. The peacock can be fragile by it self, the rubber legs seem to help with that. If I get sometime i'll tye up a couple and have Yooper help me post pictures.
Was charmed to learn that the pygmies of the Ituri forest cure eye infections by urinating in the bad eye(Trout Madness,1960).
