I have also worried about the quality of the bite...and the absence of perch. At least on the northwest side, anyways, where we almost never mark small perch anymore. In years past, the best indicator of a soon-to-be big red mark on the Vex was that the small perch vacated the area. I did see TONS of perch down on the south side this year, but I don't know how the numbers there compared to years past, either.
But yeah, the bite has been excellent for, what, three years now? We're also catching a decent mix of fish (though of course most are from the 2013 year class). The only good thing to mention, at least in my experience, is that the fish do look very healthy and fat, very unlike the fish during the "boom years" in the mid-2000's when everything you'd catch would be a skinny 26 incher.
