Holy ****!!We have the same 3 hook rule here in Tennessee. When the rig first started to hit it big everyone was running 5 or more wires with two dummy baits. well you would lose fish because sometimes they would hit the dummy. So a little custom tackle company in Soddy Daisy, TN. started making these real nice three wire rigs and that's when they started to catch these HUGE 40lb+ 5 fish sacks. on Chickamauga lake. Trust me its the best 3 hook rig you can find! Its a three wire u-rig with three spinners on the wires. They also custom hand pour their own special swim baits to go on them... Don't believe me click this...
if you want the info for Soddy Custom tackle to order some (I have several) they do not have a website. But they do have a facebook and if you call ask for Mark Grimsley and tell him that Robert with 3B Outdoors sent you.
