Sometimes you can see bluegills on your vexilar come up to your jig sniff it and swim away.  This rig will help you get the sniffers.  Tie a one foot piece of 1 lb line onto the bend of your main jig or fly, then tie on a small size 12 hook and tip it with a maggot or 2.  You'll be amazed how many more bluegill and crappie you'll hook into.
