Scientific Anglers Amplitude Smooth Grand Slam is built for saltwater situations where the cast is rarely perfect and the timing window is short. When a fish shows, you often need the line to load quickly, stabilize the loop, and turn over a fly without needing a long false-cast routine. This taper is aimed at exactly that: efficient shots at realistic distances with enough authority to hold shape in a breeze.
The “Smooth” finish is a good fit for anglers who prefer a clean feel through the guides and in hand. It keeps handling simple, shoots well, and stays comfortable over a long day of stripping, picking up, and re-casting. If you are building a setup for flats-style fishing or nearshore work where wind and fly size are part of the equation, this line is a strong choice for keeping presentations quick and controlled.
The Amplitude Smooth series of lines are, simply put, the highest-performance smooth fly lines in the world. With up to five times less drag and eight times the durability of traditional lines, this will change the way you look at fly line performance.
Tarpon. Bonefish. Permit. All in one day. All on one fly line. That's the idea behind the Amplitude Smooth Grand Slam, a 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.
