Overview

The Scientific Anglers Mastery Grand Slam Cold fly line is built for anglers chasing some of the most powerful saltwater species in cooler conditions. Designed with a versatile taper, this line excels at presenting flies to tarpon, bonefish, and permit—the legendary “Grand Slam” of saltwater fly fishing. The strong front taper has the power to turn over large, wind-resistant flies while still maintaining accuracy and control for delicate presentations. Engineered for cooler saltwater environments, the Mastery Grand Slam Cold maintains its suppleness without becoming too stiff or brittle, ensuring consistent performance in temperate flats and coastal waters. Its smooth, slick coating reduces friction, increases shooting distance, and provides excellent line management, cast after cast. Available in line sizes WF8F through WF12F, this line is suited for a variety of rods and saltwater setups. Finished in a subtle Pale Yellow/Sand color scheme, it remains visible enough for anglers while blending naturally into saltwater environments to keep wary fish from spooking.Read More +
