The Story
SA's Amplitude Smooth Trout GP is built for anglers who demand finesse, control, and distance in equal measure across varied conditions. Designed with a mid-length head and a slightly heavier grain weight (one-quarter line size heavy), it offers exceptional mending capability and accuracy at range—ideal for delicate dry fly work or subtle nymph presentations. As part of SA’s highest-performance smooth line series, this model combines long-lasting slickness with unmatched casting consistency, allowing you to put this line through the ringer while hitting rising targets both near and close.

Features
SA Line ID - Printed identification near the tip makes it easy to confirm line model and weight on the spot, so there’s no guessing which reel or spool you’re grabbing from the stack.
AST Plus (Advanced Shooting Technology Plus) - AST is SA's premium slickness additive that dramatically reduces drag and increases durability. The result: longer casts, smoother shooting, and up to eight times the lifespan of a standard line.
Improved Dry Tip Technology - Improved Dry Tip Tech is a proprietary floating treatment on the tip section that ensures superior flotation and quick line pickup. Your dry flies ride higher and stay visible longer, even through repeated drifts and mends.
Welded Loops - Factory-perfect, low-profile welded loops on both ends make for clean leader and backing connections with flawless turnover and minimal hinging.
Â
Uses
Dry Flies, Wet Flies, Nymphs, Small Streamers - A versatile, all-around trout taper designed for anglers who want smooth, precise control over a wide range of fly patterns. The Amplitude Smooth GP Line excels with dry flies, light nymphs, and smaller streamers, whether you’re working tight mountain creeks or open tailwaters.
Temp
Cold to Moderate Freshwater - Built on a supple braided multifilament core optimized for cold to moderate water temperatures, maintaining flexibility and shootability without tangling or coiling.
Taper/Weight
Mid-Length Head - A mid-length head meets a quarter-line weight heavy construction to balance delicacy and punch, offering superb line control at distance and effortless roll casting. Slightly heavier than standard trout tapers for easy rod loading and clean presentation regardless of water size.
