I'm looking for some input from anyone on here to see if they have seen this happen before... After fighting a giant after 4 hours (and losing it 30 feet from the boat), the leader broke about 3 feet from the hook. When I reeled in the rest of the line, the end of leader (180 seaguar blue label) was coiled in probably 1 inch coils for about 4-5 inches on the leader. In that 4-5 inches, the leader was extremely tight, almost like heat was applied to it. We saw the fish on top next to the boat and it was easily over 100". We thought it was wrapped around the pec fin but that's too far back on the fish for that to be the case. It also looks like it when you strip a piece of ribbon and it twists real tight. Who knows.... I've never seen this before and neither has the captain of the boat who has been giant fishing for 40+ years.
