Amplitude Smooth Anadro/Nymph and Stillwater Indicator Fly Lines


The Scientific Anglers Amplitude Smooth Anandro/Nymph and Stillwater Indicator fly lines give anglers a huge edge when casting larger flies and indicator rigs

Anadro Nymph and Stillwater Indicator lines features the revolutionary AST Plus slickness additive for superior shooting capabilities and increased durability.

What can't this line do?

Not only is this an amazing indicator line for nymphing and hopper/dropper rigs, it is also fantastic for swinging flies to steelhead and salmon. Stillwater version is awesome for long casts with chironomid rigs and indicators, and chucking big indicator rigs anywhere. Like we said, it is versatile!

One of the reasons that this line is so good at doing it all is because it is overweighted by 1.5 sizes to assist in turning over heavy rids. We recommend you still use the designated line weight for your rod when selecting the size. If using a switch rod, go one line-size up.

This line is best in moderate to cold climates.

Lines color schemes:


Scientific Anglers Premium Smooth Lines are the combination of SA's revolutionary AST fly lines with additional slickness. These lines are smooth like traditional lines, but they have increased durability and slickness due to their new smooth coating.

Each Amplitude Smooth is built with three colors for easy identification for the separate sections of the line. Welded loops provide you with easy rigging and interchanging as well.

Overall, we feel that the Amplitude Smooth Fly Lines are the finest and most durable smooth-coated lines in the world for both freshwater and saltwater applications.
