I have all three.

For a quick night on the water, we use the 13 for a couple dozen minnows. If we are going for an all day trip we jump to the size 19. If we are fishing with bigger minnows (say for walleye) we use the 19 for the day. If the bait shops are further away, we are going for a weekend, or purchasing larger amounts of bait, we use the 30.
