Scientific Anglers Amplitude Smooth Anadro / Nymph Fly Line


For Nymphing Big Rivers and Still Waters


Scientific Anglers brand new Amplitude Smooth Series of fly lines combined the slickness and durability of their proprietary AST Plus with a classic smooth fly line coating. Eliminating the “humming” sound found in the standard Amplitude and Wavelength fly lines. These lines are smooth like traditional fly lines but have increased durability and slickness due to the addition of the AST Plus coating.  The Anadro / Nymph Amplitude Smooth fly line comes in a single color style with three differentiating color-ways (Moss/Willow/Orange) to help quickly identify the separate parts of the line, they also come with the standard welded loops for quick and easy rigging.

The Anadro / Nymph fly line has quickly become the go-to line of choice when fishing clunky nymph rigs and larger dry-dropper setups. The half-sized heavy aggressive front taper turns strike indicators and split shot over with ease while the elongated rear taper offers greater line control over further distances.

• Features the revolutionary AST Plus slickness additive for superior shooting ability and increased durability

• Long rear taper for extended line control and long-distance casting; the best nymphing taper we offer

• An unbelievable indicator line for nymphing up trout and bass or swinging flies for steelhead and salmon; excellent for double-nymph rigs or hopper-droppers

• Overweighted by 1.5 sizes to assist in turning over heavy rigs; use designated line weight for your rod

• Use one size heavy for switch rods

• For use in moderate and cold climates

• Braided multifilament core
