Last year, I got a pair of downriggers and a FishHawk speed/temp probe for salmon fishing. It's nice knowing the 'downspeed' (speed at downriggers all down vs surface speed). Anyway, I ran an experiment all last season. I'd run the downrigger about 12 ft off the bottom with a shallow diving crankbait (reef runner 500 series) back about 100 feet on light spin casting tackle. This put the crankbait about 3-5 feet off the bottom. This rod provided fair action with smallmouth, catfish, and large sheephead, but only a single walleye all season and that was on the Lorain Sandbar in September. I thought I'd pick up large bottom oriented fish, which I did, except they were not walleye
