I have the book as well although I reference it less than nearly on - it( and tips from rps and others that precision troll) has increased my take home exponentially. I was out early(sort of, 0730-0930) before it got absolutely ridiculous this morning on LOZ and picked these up contour trolling #7 flicker minnows at 22ft. Had the usual undesirables as well(bass, drum, channel and blue catfish) with the walleye 20.5" and biggest crappie 13.5".
