My father taught me to rig that way 20 years ago for southern panfish using catalpa worms, single wiggler or earthworm grub. In recent years I've modified the rig 8 foot noodle rod, using 1/4 ounce sinker on bottom, #12 mustad fly (long shank) hook. Changed the bait to wax or mealworms, small crickets, or red worms. It's effective fishing vertical from a flat boat near stumps.
