Good looking jugs. They should work great on lakes, ponds, coves, backwaters, and even small rivers. However, if you freefloat them in the current of a large river, you may find that they get so scattered that it becomes difficult to see them. Also, if you're jugging in the channel where barges are common, it's not unusual to lose a few when the barge runs over them. Since I mostly jug the Arkansas River, I use painted 2-liter soda jugs for greater visibility and less expense. Three or four ounces inside the jug will cause it to flag on a bite, just like the foam noodle.
