Scientific Anglers Mastery MPX Fly Line


The updated version of Scientific Anglers®’ legendary GPX all-purpose line. Mastery MPX Fly Line offers all the powerhouse shootability that made the original so popular, but with a greater emphasis on presentation. Its braided multifilament core supports an improved taper, and features advanced ST+ slickness additive for effortless flow and easy control. Meanwhile, Scientific Anglers built this line a half-size heavy, with additional mass toward the front of the head, to provide the power needed to sling big streamers and turn over large flies without missing a beat. Your rod will load as easily as ever, yet you’ll have more control than you ever thought possible in an all-around fly line. Welded loops on both ends.
