The Misty Grey Tournament Line is the ideal choice for big-game fishing, where nylon must withstand powerful surges without compromising line strength. Its IGFA compliance meets the needs of anglers seeking a line certified for competition or record attempts. The copolymer offers a balance between strength, knot strength, and the ability to absorb powerful runs. Its high strength makes it suitable for setups designed for tuna and long-distance fishing under heavy pressure. The choice of diameter depends on the desired strength, the reel’s capacity, and the desired margin of safety during the fight.
