Fly Lines: What's the Difference?
Choosing the right fly line is just as important as selecting the perfect fly rod. With various types available, understanding their differences will help you improve your casting, presentation, and overall success on the water. Let’s break it down.
Types of Fly Lines
Fly lines are categorized based on their weight, taper, and density. Each plays a role in how your fly performs in different fishing conditions.
Weight
Fly lines are weighted to match the rod they are used with, measured from 1 to 12. The right weight ensures efficient energy transfer from the rod to the line, affecting casting distance, accuracy, and the size of flies that can be used.
Lightweight (1-4) – Ideal for small streams and delicate presentations. Best for fishing small dry flies and nymphs where precision and subtlety matter.
Midweight (5-7) – Versatile for trout, bass, and steelhead in rivers and lakes. These weights balance power and finesse, making them the most common choice among anglers.
Heavyweight (8-12) – Designed for big-game fish and saltwater applications. These lines are capable of casting large flies, handling strong winds, and fighting powerful fish.
Taper
Taper affects how energy transfers through the line, impacting accuracy, presentation, and distance. The right taper enhances casting efficiency and precision, making it essential to match your fly line taper to your fishing style.
Weight Forward (WF) – The most common taper, with extra weight in the first 30-40 feet of the line. This design makes casting easier, helps with distance, and provides better control in windy conditions. Ideal for beginners and versatile enough for various fishing situations.
Double Taper (DT) – This taper has a gradual increase in weight on both ends with a thinner middle section. Double taper lines excel in roll casting and delicate presentations, making them a favorite for small streams and traditional fly anglers. They are also more economical because they can be reversed when one end wears out.
Shooting Taper (ST) – Designed for maximum distance, this taper has a short, heavily weighted front section that helps generate high line speed. Often used in saltwater, spey casting, and heavy streamer fishing, shooting tapers allow for long, powerful casts with minimal effort.
Density
Density determines whether a fly line floats, sinks, or does both, influencing how the fly is presented to fish.
Floating (F) – Stays on the surface, best for dry flies and general use. Floating lines are the most versatile and widely used.
Sink-Tip (F/S) – Partially sinks, ideal for nymphs and streamers in deeper water. This type allows anglers to keep their fly at a desired depth while still having control over line management.
Full-Sinking (S) – Sinks completely, useful for deep lakes and fast currents. These lines come in different sink rates, allowing anglers to target fish at specific depths.
Intermediate (I) – Slowly sinks, perfect for fishing just below the surface. These lines work well for fishing in lakes or when fish are feeding just beneath the water's surface.
Matching Fly Lines to Your Fishing Style
Small Streams & Dry Flies – A weight-forward floating line in 3-5 weight ensures accuracy and delicate presentations. Double taper lines can also be beneficial for short, precise casts in small creeks.
Big Rivers & Nymphing – A weight-forward floating line in 5-7 weight helps with roll casting and long drifts. Sink-tip lines can be useful when fishing deep pools and fast currents.
Saltwater & Heavy Winds – An Over-weighted taper floating or sinking line in 8-12 weight provides power and control. These lines allow for long, accurate casts and can handle large flies needed for saltwater species.
