Scientific Anglers Mastery MPX Fly Line

One of the most popular fly lines for many years now, the Scientific Anglers Mastery MPX line provides the ultimate in freshwater and light saltwater versatility. A redesign of the popular Scientific Anglers GPX fly line, this line is built as a do-it-all freshwater line great for lakes, streams, rivers, and more. What's better? The line's taper and design cater to a variety of angling methods including streamer fishing, dry fly fishing, and heavy nymphing. If you're looking for the most well-rounded, versatile line on the market, you've come to the right place.

Features

SA Line ID and AST - AST stands for Advanced Shooting Technology. The Mastery MPX from SA has superb shooting capabilities and allows anglers to quickly cast any fly from a boat or from the bank. The line also features a couple of different color schemes for anglers who prefer to choose their line color. SA has also included an easily identifiable line ID so you can quickly tell which line you're fishing when changing spools.

Uses

Large Dries, Nymphs, Streamers - The MPX is designed as a freshwater trout line. SA made this line for larger dry flies, heavy nymphs, and even small-medium sized streamers. This line is also great for picking up large dries from a drift boat or streamers on the lake and quickly recasting/ shooting line. This isn't the best line for small dry fly presentations, small creek fishing, or slow action rods (fiberglass, bamboo, etc.). It's also not a great line if you're trying to carry a lot of line in the air to land a fly on a dinner plate at 60-feet.

Temp

Cold/Moderate - This line is made to be used in a variety of conditions including freshwater streams and rivers, lakes almost any climate. That being said, this line will turn limp in tropical climates and isn't meant to be used in high heat.

Taper/Weight

More Mass Toward the Front of the Head - Built a half-size heavy, the Mastery MPX line has a short front taper. The MPX taper is built to load fast-action rods for power and accuracy at distance. Most of the line's mass is found in the first 20-feet of the head and the head is shorter and heavier than other dry fly specific lines (36-foot head length on the WF5F version). This helps anglers quickly load fast-action rods and shoot line at longer distancesÉ think quick shots with larger dry flies from a drift boat.
