The Momoi 14050 Hi-Catch 50-Pound 280-Yard Smoke Blue Line is an extremely high quality monofilament line produced using strict quality controls. It exhibits very low memory characteristics and is very soft and flexible while maintaining a high tensile strength to diameter ratio. Smaller diameter lines with high tensile strength result in larger reel capacity when fighting hard charging game fish. Comes as a spool. Momoi Fishing is the pioneer of fishing line developments. In 1951, it became the first company in the world to adopt synthetic fiber as the material for fishing lines.
