Whitefish Chain Help

[kuenro02]

Hey everyone. New to the site but excited to learn more about walleye fishing. Were on a vacation to the whitefish chain near brainerd and have yet to catch a walleye. All I've been catching are small northerns. I've tried trolling cranks, livebait harness with crawlers and leeches, slow death behind bottom bouncers and jigging a lead head and leech. I've tried along weed lines in 18-23', mid lake humps and shallow flats in the evenings. Not sure what else to do but not what I was expecting out of the trip. ANY help would be appreciated! Thanks and ill be checking often since I don't have much time left up here. Thanks
