Fishing in northern Canada we where motor mooching for kings with a single action knuckle buster in about 250' of water. I had 30 pulls of 17# line out with 14# leader, when a big hali decided to take my herring. An hour and fourty five minutes later I landed a 178 pound hali. To this day I dont know how the leader didnt snap. I'm not sure of it was the luck or punishment, it was almost not fun after an hour.
