What’s the Use of a Fly Line?

As a beginner angler, you might wonder what the use and importance of a fly line is. Simply put, a fly line is used to present a fly to the fish that you aim to catch.

Since there are different water bodies and species of fish with unique characteristics, fly lines come with different features.

Floating fly lines are used to fish on topwater columns while sinking lines are effective for the bottom levels. There are also different taper types as well as sink rates.

Things to Consider When Buying a Fly Line

There are many fly lines on the market, and as such you must be intentional about what you want.

In order to help you make the right choice of fly fishing line, we have discussed below vital features to look out for.  

Fly Line Type

There are three main types of fly lines, with each one serving a unique purpose. These lines are floating fly lines, sinking fly lines, and sinking tip lines.

Floating fly lines are designed for fishing on the surface level and are best suited for fishing dry flies, nymphs, and streamers. As the name suggests, sinking lines go down to the bottom levels of the water.

Sinking lines are the best fly lines for fishing in lakes, ponds, and dams. A sinking tip line is a hybrid of a floating line and a sinking line. When using this type of line, only the tip sinks leaving the other part floating on topwater. 

Sink Rate

The sink rate of a fly line determines how fast the line goes down into the water. The sink rate is usually calculated in inches per second (IPS).

The location where you are fishing should inform the sink rate of your fly fishing line. For deep rivers and lakes, a fly line with high IPS works best. For a shallow river, a lower IPS is best. 

Fly Line Taper Type

The taper of a fly line refers to the structure of the line, in terms of weighting in certain areas. The taper of a fly line determines the level of control that you have over fly presentation, as well as the casting distance that can be reached.

There are two main types of fly line taper which are double taper and weight forward taper. 

A double taper fly line is tapered at either end with the middle section being the thickest part of the line. The structure of double taper fly lines means that you can cast with both ends.

Double taper fly lines are great for trout fishing. They are best for making delicate presentations but do not work well in windy conditions.

The front end of weight forward taper lines are usually heavier than the rest of the line. Due to the forward weight, you can cover a long casting distance and fish heavy flies.

Weight-forward fly lines are suitable for fishing in windy conditions.   

Weight 

The fly line weight should match your fly rod and fly reel. The weight of a fly line varies from 1 wt to 14 wt. For freshwater fishing, the requirements range from 1 wt to 7 wt. For saltwater fishing, it is from 8 wt to 14wt. 

Length

The presentation is the most important thing when it comes to fly fishing. As such, you do not need a fly line that is too long.

The average fly line is around 100 feet and that is usually enough for most casting distances. Other features to look out for include color, coating, and loops. 

Conclusion 

A fly line is essential for the presentation of your fly and determines how effective your setup is. This is why it is important to get a suitable and reliable fly line for your fly fishing.

Always make sure to look out for features such as length, weight, sink rate as well as fly taper line when purchasing a fly line. In conclusion, always combine your fly line with efficient fly rods and leaders for the best result.
