This sounds like its gonna be an interesting swap. Hopefully a few more sign up. Walleye although a predator are IMO lazy and eat anything that moves and is close to their mouth. Thus, presentation is everything. In my experience, most are caught in 15 - 25 FOW. They eat nightcrawlers, crawdads, and Shad along with any fish they can swallow. Only thing I haven't seen in their gut is catfish.
