Scientific Anglers Amplitude MPX Fly Line For Trout Anglers Delivers Floating Long Distance Accurate Casts And Delicate Presentations

S.A. Amplitude MPX from Scientific Anglers represents the next leap in distance, durability, and presentation for trout and other freshwater species. Built to load fast on modern, quick-action rods, MPX blends power with finesse to deliver accurate casts and delicate dries, even when the wind picks up.

Designed with the AST Plus slickness additive, MPX shoots farther with less drag and lasts considerably longer than competing lines. The result is a line you can rely on from first cast to last drift, season after season.

• AST Plus slickness for distance and durability. 40% less drag than lines without the additive and a lifespan more than 60% longer, so you spend less time retackling and more time fishing.
• Front-loaded taper with extra mass in the head. Enhanced turnover and presentation, especially with larger dry flies, nymphs, and streamers, while preserving the line’s power for longer casts.
• Floating tip texture for optimal flotation. Keeps the line up and ready, reducing impulse dips and enabling quicker pick-ups in shallow waters.
• Shooting texture running line. Smooth, distance-focused casts with less resistance through the guides, even in cooler conditions.
• Front and rear welded loops. Quick, secure connection to your leader and backing without fuss or fiddling.
• Braided multifilament core. Strength, sensitivity, and loops-in-tension feel, so you can feel subtle takes and fight fish with confidence.
• Triple-textured, tri-color design. Aids in line visibility and tracking during retrieves and casts in varying light.
• Half-size heavy to load fast-action rods. Faster loading for quick turnover and tight presentation across a range of rod actions.
• Ideal for large dry flies, nymphs, and streamers; versatile in moderate and cold climates. A line that handles a broad set of trout scenarios—from meticulous dries to aggressive streamers.
• Advanced GPX lineage, refined. MPX is an improved version of the GPX taper, delivering a more refined balance of power and presentation.
• Line weights and colorways. Available in WF3F through WF9F with Optic Green, Moss, and Buckskin color accents to suit visibility and water conditions.
