Scientific Anglers Mastery MPX

Power with Precision—Your New Favorite All-Around Line.

The Mastery MPX from Scientific Anglers is the do-it-all fly line that doesn't flinch—whether you're bombing streamers into the wind or laying down a dry-dropper with pinpoint accuracy. It's built a half-size heavy to load rods quickly, especially today's fast-action setups, and carries more mass to the front for extra punch and control.

With a versatile taper and SA’s slick AST coating, MPX gives you high performance without being overly aggressive—it’s a line that handles big flies and big water just as well as delicate dries when you need to tone it down.

This line shines on windy days, when fishing hopper-dropper setups, or when you need to push a size 6 streamer into tough structure. If you’re only carrying one line for a western trout trip, this is the one.
