My local tackle guy is selling pre-tied catfish leaders. They are about 16" in length with a torpedo sinker, a 50# shock leader, and some cheapo steel hook that seems really flexible. http://www.transpeninsularoutfitters.com/hooks-pages/images/sinkers-torpedo-single-thumb.jpg 1. Has anyone ever used a rig like this? 2. Has anyone ever used a torpedo sinker in place of a sliding sinker?
