I agree with going out with either charters or other folks. There is a ton of little tips that can make every trip better. From locating fish, finding the right water to the running of boards and lures and knowing when to run what. Trolling just to troll and not catching can get boring for most, quick. It is those times where the fire drills start that keeps folks hooked on trolling. Like mentioned, you need to think about do you want to pull meat. Dipsies, cranks, spoons and start from there. With the boat you have, do you drift and cast now? That is still a very good effective way to catch walleye.
