Scientific Anglers Mastery Trout Standard Fly Line

Don’t let the name of Scientific Anglers’ Mastery Standard Fly Line, because it’s a fly line that far exceeds the term“standard.” The Mastery Standard Fly Line is a floating line that’s true to AFFTA (American Fly Fishing Trade Association) line weight casters fly line. Designed to make accurate presentations, smooth casts, and flawless mends, the Mastery Standard Line has a mid-length head and a true-to-line-weight construction that’s all built on a  braided multifilament core. Whether you’re casting large parachutes over evening risers on the West Branch or nymphing pockets first thing in the morning, the Mastery Standard Fly Line can handle all of your needs. 

Features

SA Line ID and Advanced Shooting Technology - Often referred to as the “caster’s fishing line,” the Mastery Standard series has features that make it an effective tool that’s a pleasure to cast. With their Advanced Shooting Technology (AST), Scientific Anglers utilizes a patented dry-slick technology that achieves continual line slickness and an ability to shed dirt, grime, and other water-borne contaminants. And to make for quick identification, Scientific Anglers adds their SA Line ID, which is a unique identification system found at the first 1’-2’ of the line’s tip. 

Uses

Nymphs, Dry Flies, and Wet Flies - Designed for fishing just about anything that you need to fool a trout, this line is a sure bet whether you’re drifting dry flies or plunging nymphs. With a mid-length head, this line makes for accurate and soft presentations and it can deliver just about any fly in your box.  

Temp

Cold/Moderate - A solid choice for all trout angling, this line handles cold water situations with ease, and if you find yourself on a warm bass pond, you can use the Mastery Standard Fly Line with confidence. However, if you try and fish it in a tropical situation, you’ll notice the line getting soft and going limp.    

Taper/Weight

More Mass Towards the Front of the Head  - Built to be true to its line weight with a mid-length head, the Mastery Series ensures clean casting and solid accuracy. Adding more mass towards the front of its mid-length head allows you to make nice and long casts that won’t feel overpowred, and since it’s made true to its line weight, this line gives enjoyable casting every day of the year.
