I have been out a couple times targeting crappie trolling #4 flicker shad and #7 slicker shad on leadcore line in 25 -30ft of water with some success along the front of docks. I have only been letting out 60 to 65 ft of line or two colors of lead core which should keep those crankbaits between 18 to 22 feet down at 1.7 mph to 1.4 mph. Not sure if this helps but has been working for me. Numbers are nothing to brag about but quality fish for sure most have been 12" to 14".I have not had the time to target any walleye like I want going to try it this fall when the lake calms down.
