Swing for the fences with the Scientific Angler Smooth Grand Slam Taper Fly Line. It was designed specifically with the elusive goal of landing tarpon, bonefish, and permit in one day, all on one line. The short, powerful head cuts through persistent coastal breezes and easily turns over crabs, shrimp, and tarpon toads. It's over-weighted by 0. 75 sizes to load rods quickly, and Tropi-Core technology remains stiff and slick in hot, humid environments. AST Plus slickness additive ensures superior shooting ability and smooth presentations, so you can reach distant, fast-moving targets. The Grand Slam is up for the challenge.
