Interesting observation Wrench. Ive seen similar mixed results, but all from deeper main lake points (haven't fished shallow). Some lean, rough looking fish and some real healthy feeding up fish. Night and day difference in fish from the same school. I attributed it to the wide variance in spawning times, but that doesn't explain the sores and bad condition of some of these fish. I did note that several of the bad looking fish appeared to have been caught before. Good question for Greg Stoner.....
