    The Scientific Anglers Mastery Trout Fly Lines are the perfect choice for chasing trout of all types and sizes. Mastery Trout has a extended head, making flawless dry fly presentations at any distance. This line is also ideal for nymphs and smaller streamers. Mastery Trout loads rods smoothly at any distance, throws tight and accurate loops and will not spook wary trout.

    These lines are proven performers and feature the AST Plus Slickness Technology to effortlessly shoot line further. AST Plus also makes Mastery Trout the most durable line, maintaining its slick properties 8 times longer than other fly lines. Mastery Trout also excels at line control, roll casting with ease, and mends line effortlessly for perfect, drag free drifts. This is the versatile trout line of choice for lighter all-purpose trout fly rods.

    • Features the revolutionary AST Plus slickness additive for superior shooting ability and increased durability

    Bought this line as a 2wt for my Hardy Ultralite rod. Expected a “standard” performance but was surprised by great handling and shooting properties. Highly recommend.

    just received this line earlier today (4wt). loaded it onto my 8' creek rod and took it straight out. awesome line. smooth, delicate, yet has the power to turn over both larger terrestrials and indicators.

    Great glass line
    JO (ME) | February 26th, 2021
    I use this line on my glass 4 and 5 wts and it works great. I’m using throwing dries or small wet flies. The line is true to weight, lands gently, and the long head make mending and longer casts a breeze.

    Just purchased this 3wt line and can't wait to fish with it. Thanks to RFR I get what I need when I need it in short order. Great company to buy from. Highly recommended. Tight lines.

    Great Mends
    Chris Firkus (WI) | May 8th, 2020
    Great long belly for mending while swinging wets downstream. Subtle presentation. This is my second copy of this line. The welded loop failed after one season on the last line, but a nailknot is no reason in my mind to drop a star.

    Great all purpose line
    DL (San Diego) | April 5th, 2020
    I threw this line on my 3wt, which gets used for dries and some light nymphing. It's done both well and I haven't had any issue with the performance at all. I would rate it a tad stiffer than RIO gold but not in a bad way. It floats well and is easily visible. All in all, I would buy again

    Scientific Anglers Mastery Trout Fly Line is the last line of dry fly, essential for small streams, using a 2WT rod, you will have an incredible experience fishing small trout. Like all Scientific Anglers lines, this is a 100% recommended wonder. You will enjoy it to the fullest. A great big line.

    The Scientific Anglers Trout Line is one of the best trout lines I've used. I like the presentation I'm able to achieve with this line. It casts well. I think this is a good all-around line that I will use for a long time -- I've read it's durable!
