How do I know what fly line to use?

Purchasing a fly fishing line involves considering several key features to ensure you select the correct fly line for your specific needs. Here's a complete overview of the thought process, including the important factors to consider:

Line Weight (WT):

Fly fishing lines are designated by weight, ranging typically from 1 to 12 WT. The line weight should match the weight of your fly rod for optimal performance, offering a "balanced outfit". Lighter lines (1-5 WT) are suitable for small fish and delicate presentations, while heavier lines (6-12 WT) are used for larger fish and casting larger flies.

Line Taper:

The taper refers to the gradual change in diameter and thickness of the fly line from one end to the other. There are three main types of tapers or fly line profiles: - Weight Forward (WF): Most common and versatile taper, with a thick front weighted section that aids in casting distance and provides better control at shooting distances. - Double Taper (DT): Thicker in the middle and tapers down on both ends, can offer delicate presentations and better accuracy at shorter distances. - Shooting Taper: Specialised taper designed for long-distance casting and targeting fast-moving fish. It has an extremely thin running line (can be a separate running line) for less friction through the fly rod guides.

Line Material:

Fly lines are typically made from one of three materials: - PVC (Polyvinyl Chloride): Commonly used for fly lines and is durable. It performs well in a variety of conditions. - Coated: Some lines have a coating applied to the core material, enhancing slickness for longer casts. - Braided Core: Provides added strength and flexibility, allowing for better control and casting accuracy. - Mono Core: Can be used to make fly lines stiffer and also used to make clear fly lines

Line Density:

Fly lines have different densities to determine their buoyancy and sink rates. The main types are: - Floating (F): Stays on the water's surface and is suitable for most freshwater and saltwater fly fishing applications. - Intermediate (I): Sinks slowly, ideal for fishing just below the surface or in shallow waters. - Sink-Tip (ST): Combines a floating section with a sinking tip, allowing for fishing at different depths. - Full Sinking (S): Entire line sinks at a controlled rate, useful for deep-water or still water fishing.

Line Colour:

While colour does not directly affect performance, it can influence visibility and stealth. Brightly coloured lines are easier to see, especially in low light conditions, while muted or camouflaged colours are less likely to spook wary fish. Please note that most Hi-Viz fly lines are only viewed us a shadow against the sky from fish below the surface.

Line Length:

Fly lines typically come in various overall lengths, usually ranging from 80 to 140 feet. Fly line head lengths are also a consideration with longer headed lines offering greater casting distance, while shorter lines can be easier to cast and control in tight spaces.

Manufacturer and Price:

Consider reputable brands known for their quality fly fishing lines. Compare prices, read reviews and seek recommendations from experienced anglers to ensure you're purchasing a reliable and durable product within your budget. Please contact our dedicated sales team if you require further guidance.

Specialised Lines:

Depending on your fishing needs, you may require specialized lines such as saltwater fly lines, nymphing lines, pike lines or Spey casting fly lines. These lines are designed for specific fishing conditions and techniques.

Remember to match the line weight to your fly rod, as this is crucial for optimal fly casting performance. Additionally, consider the specific fly fishing environment, target species and casting preferences to choose the most suitable fly line.


It's always a good idea to visit a local fly shop or consult with experienced anglers who can provide personalized advice based on your fishing requirements.
