Scientific Anglers Amplitude Textured Fly Lines represent the highest level of development in fly line technology. A full range of features help to extend the life of the line and improve line performance during the cast and on the water. The “heart” of these lines, the core, is designed to give top performance. The core material varies depending on the specific use of the line. Unique line taper designs maximize turnover and presentation of the fly. Line coating formulations are designed for specific temperature ranges and include the patented AST Plus additive that gives you the farthest shooting, longest lasting fly lines on the market. In addition to AST Plus, the full range of features on Amplitude Textured Fly Lines also includes the SA Line ID to quickly find the line you need. Improved Dry Tip keeps the leader from pulling the line tip below the surface. Welded Loops allow leaders to be changed quickly and easily. Floating Texture allows easy line pick up from the surface, while the Shooting Texture decreases line friction for maximum casting distance with minimal effort. The Tactile Reference Point allows you to feel when the line is at full load. Additional features are present on specific lines. From trout to tarpon and beyond, there is an Amplitude Textured Line for every fly-fishing application. These lines represent the pinnacle of fly line development and will make your on-water experience more enjoyable and successful. These lines combine slickness, durability, and performance into the best fly lines you can buy. ONE QUARTER HEAVY LINE Features the revolutionary AST Plus slickness additive for superior shooting ability and increased durability Floating Texture on the tip section for the ultimate in flotation; it simply keeps dry flies floating longer Shooting Texture running line delivers longer casts, thanks to a reduction in friction Mid-length head for exceptional mending and accuracy at distance The casters line Braided multifilament core
