I am a little biased but Pool 2 gets my full swinged head nod! Its tough to go to a place as close as the metro and have a good a shot at catching a fish of a lifetime as Pool 2 of the Miss River offers.
For numbers of walleyes however, I think there are some better metro lake opportunities that could offer up plenty of action of 14″-20″ walleyes. IMO, I think the Twin Cities metro area has a good selection of walleye lakes within a stones throw from each other that offer up an abundance of eating sized walleyes.
