Description
Scientific Anglers Amplitude Smooth Double Taper is a true to weight floating line for anglers who enjoy classic casting feel on bamboo, glass or medium action graphite rods. The balanced double taper loads smoothly at short to medium range supports delicate dry fly presentations and offers excellent mending control for nymph or indicator work in rivers and stillwaters.
Technologies
- AST+ – Advanced slickness coating that reduces friction, improves shootability, and maintains slick performance far longer.
- Shooting Texture – Rounded embossed pattern that reduces friction boosts durability and improves shooting distance.
- Floating Texture – Diamond-shaped embossed pattern that increases flotation and enhances line ride for superior performance.
- Welded Loops – Durable welded loops on both the front and back of the line for easy reliable loop-to-loop connections to backing and leaders.
- SA-ID – Printed line identification system showing taper weight and density for quick recognition.
- Braided Multifilament Core – Supple cold-water core that improves flotation reduces memory and provides smooth stable casting.

Amplitude Smooth Line Features
Scientific Anglers took their revolutionary AST Plus slickness additive and put it into the Amplitude Smooth Series. These lines are smooth like traditional lines, but have increased durability and slickness due to the AST Plus, which is mixed directly into the coatings.
Each line is built with three colours to identify the separate parts of the line, and welded loops for quick and easy rigging.
