its pretty much luck of the draw, if you keep catching smaller fish in one spot, then you might try another spot. here on lanier schools of them might have all small fish move a few docks down and you can catch a larger fish. in spring my big fish came from deeper water away from the beds and the beds had the smaller fish. but if your catching fish then stay where your at. cant go wrong with catch-n, its better then looking around allday for the one you might not find
