Early in the morning when the Rainbows were still feeding high in the water for bugs, we floated marshmallows and they NAILED them. We figured this out too late in the morning so floating the marshmallows needs to be done BEFORE the sun hits the water. Once the sun hit the water the fish moved to the bottom. We then used power bait with a marshmallow an inch above the hook to help if float off the bottom. Came home with 3 nice Rainbows that went into the smoker.
