Tarpon. Bonefish. Permit. All in one day. All on one line. That’s the idea behind the Mastery Grand Slam, a fly line designed specifically to help you achieve one of angling’s most elusive accomplishments. With a short, powerful head the Grand Slam cuts through wind and turns over crabs, shrimp, and tarpon toads with ease. We’ve got the line. You just need the fish.

    • Short, powerful head for quick casts to moving targets
    • Overweighted to load rods quickly and efficiently
    • Tropi-Core™ technology for tropical climates
    • SA ID – SA MS SLAM WF X F (X = line weight)
