For those who troll crankbaits, they have the Troller's Bible which tells depth with amount of line out for different crankbaits. But what about those of us who troll double 1/16 oz. jigs. Here's the question.......if you are trolling at 0.5 mph using 10 lb test monofilament line how much line out do you need to run the jigs at 10 ft deep? Is there a book that tells that?
