Scientific Anglers Amplitude Smooth Trout Fly Line
The Scientific Anglers Amplitude Smooth Trout is a premium floating fly line designed for anglers who demand exceptional presentation, precise line control, and effortless casting performance. Built on Scientific Anglers' proven Trout taper, it features a long front taper that delivers delicate presentations with dry flies, nymphs, emergers, and small streamers. Whether fishing technical spring creeks, freestone rivers, or stillwaters, this line provides the finesse needed to fool the most selective trout and grayling.
Amplitude Smooth Trout incorporates AST Plus (Advanced Shooting Technology Plus), creating one of the slickest smooth-coated fly lines Scientific Anglers has ever produced. The ultra-low friction coating allows the line to shoot effortlessly through the guides for longer casts, greater efficiency, and exceptional durability. A braided multifilament core provides excellent flexibility with low memory, while factory-welded front and rear loops ensure fast, secure rigging on the water.
