Scientific Anglers Amplitude Textured Grand Slam Fly Line

| /

Scientific Anglers Amplitude Textured Grand Slam Fly Line is a high-performance fly line designed for saltwater fishing. It is specifically engineered to help anglers achieve longer casts, better accuracy, and improved line control.

The line features Scientific Anglers' patented AST Plus slickness additive, which reduces friction and enhances shootability for improved casting performance. The line is also textured, which helps to reduce surface area and increase buoyancy, resulting in better floatation and easier mending.

The Grand Slam line is a full-floating line with a weight-forward taper, which makes it ideal for targeting a variety of species in different saltwater environments. The taper helps to provide a smooth, consistent cast, while the textured surface of the line helps to reduce memory and improve line control.

The line is also designed with a short front taper and a heavy head, which allows for quick loading and effortless turnover of large, heavy flies. The Grand Slam line is available in a range of weights, from 6 to 12, making it suitable for a wide range of saltwater species, including bonefish, permit, tarpon, and other hard-fighting game fish.
