Used this line on a tarpon fishing trip in the Caribbean. The high-contrast sighter made it easy to track the line during long runs. The 100lb loops gave me confidence when fighting a large fish. The line performed well under heavy pulls and didn’t break.

Felt more durable than other floating lines I’ve used. The AST+ additive helped with casting distance. A bit expensive, but worth it for saltwater big game fishing.

Fished on a remote reef with giant trevally. The line held up well under strong pulls. The sighter was very useful when the fish was running far out. No line failure during the entire trip.
