I need help with my mooching rig set up and would appreciate any advice from the charter skippers out there. I've been tying up tandem #4 octopus hooks with 30 lb mono, but whenever I have guests on board who don't fish very often, we break off way too many salmon. The point of break is usually the mono between the two hooks. I tie them with standard egg loop knots so the troll hook is fixed and doesn't slide. It would seem that 30 lb mono for a 10'ish lb fish would be plenty, but nope. Do I go to 40 lb mono? Just put up with it? Other strategies? Thanks!
