Being able to cast a hundred feet out may look sweet, but how many fish have you actually landed from that far out? Being a more refined version of the super-powerful GPX taper, the Scientific Anglers Amplitude Textured MPX Taper Fly Line quickly loads modern fast-action fly lines while maintaining the ability to make more delicate casts when you're confronted with a short-distance casting scenario. And since a line that casts like a dream but immediately sinks once it hits the water is basically worthless, Scientific Anglers finished the line off with its AST Plus slickness additive and added an extra floating texture on the tip to keep your line (and fly) riding high on the surface.
