Mastery lines represent the pinnacle of our smooth line technology. No matter the species, no matter the situation, we’ve built a line for it. Everyone from dry-fly trout purists to pelagic enthusiasts will find the line they need to catch the fish they crave.
The Mastery Infinity has the power to bomb out streamers, yet retains delicacy for dry flies. It mends like an absolute dream, and delivers flies at all distances. Built a half-size heavy, with a long head and substantial front taper, it’s perfect for everything from trout and panfish to pike and steelhead. There’s a reason we call it the Infinity: there is no end to what you’ll be able to do with it.

For years, the gold standard in the Scientific Anglers lineup was the GPX taper. From tossing small dries to slinging huge streamers, the GPX could do it all. But all good things must come to an end. Built a half-size heavy, the MPX taper starts where the GPX left off. Redesigned with more mass toward the front of the head, the MPX provides the same benefits of the GPX, with an added emphasis on presentation. The power is still there, only with an added bit of finesse. Meet your new best friend and the best all-around fly line we’ve ever made.
