Buying Guide: How to choose the best fly line

Scouting for a best fly line can sometimes be a daunting and challenging process. This is because the market is flooded with a wide range of types and sizes. Getting the right fly line requires some level of research and knowledge of what your needs are.

Regardless of whether you are an amateur or a seasoned veteran, here are a few points you can use to assist you in getting the right fly fishing line.


At present, most fly lines don bright colors such as yellow and red, which makes them easily visible. However, there is no better, brighter color than the other; all that matters is your taste and preference. According to fishing experts, fly fishing lines that are bright tend to be ideal when fishing with floating lines. Conversely, fly fishing lines with a subdued color like grey or dark green tend to be excellent when fishing using a sinking line.

Loop stability

One of the most significant aspects that make fly lines so unique is their casting capability. And to have a perfect cast, loop stability undoubtedly should list among the attributes your fly line has, since without this feature, your fishing experience could be compromised.

According to fishing pundits, loop stability happens to be the leading determinant of an exemplary casting line. It determines the ease with which your fishing line unfurls while casting, and thus establishes whether you get a pleasant or a bad cast.

A line with good loop stability tends to ensure the fly’s speed does not get too low. This enables it to fight the effects of gravity. If your line lacks proper loop stability, the other aspects that determine a good cast, such as weight and distance, will not have any impact.


Fly lines come in different weights and are measured in grains. The lines range from 1–weight (60 grains) to 15-weight (550 grains). The fly fishing line’s weight is significant as it directly impacts the fish you intend to catch and the type of fly you will use.

Usually, heavy fishing lines tend to make a lot of noise during casting, scaring any target fish approaching. It is always best to use a light fly line when fishing for lightweight trout.

On the contrary, if you intend to use a large streamer with a light fishing line, you might have poor control over the fly and the cast. You can use the following tips to choose the suitable weight for your line:

  • 1– to 3-weight: Suitable for catching small fish and larger trout that inhabit tiny streams.
  • 4-weight: They are ideal for catching large trout where the fisherman does not have to make long casts.
  • 5-weight: They are suitable for all-round trout fishing.
  • 7-weight: Ideal for fishing in larger rivers
  • 8-weight and above: Ideal for fishing saltwater fish in large rivers and lakes.

Casting distance

The fly line’s casting distance depends on the size and material used in making the line. If the fishing line happens to be huge and thick, you might not be able to cast long distances than when you make use of thin and light fishing lines.

Therefore, it is always best to settle for a fishing line made of light material to give you extra casting distance.

Fly fishing line tapers

Due to the vast assortment of tapers in fly fishing lines, selecting the best can be a time-consuming task, especially for amateurs. Typically, tapers determine how energy is distributed during the casting process. Most fly fishers prefer a weight-forward taper due to its ability to handle casting sessions in both still and moving water.

At present, the market is witnessing the growing popularity of double tapers, although they are only limited to short and medium trout found in moving water only.


The outer coating on a fishing line plays an instrumental role in determining the fishing tool’s durability. At present, many manufacturers prefer applying a PVC coating on lines due to their flexibility, softness, and durability attributes. Other manufacturers choose to use polyurethane as a base material, ensuring the fishing line remains resistant to cracking for extended periods.

Types of fly fishing lines

At the moment, there are 3 basic types of fly lines, namely:

  • Floating fly line: This is by far the most standard used fly line, and it does precisely what the name suggests, floating. If you are a beginner in fly fishing, you might want to use this line for your fishing expeditions.
  • Sinking fly line: They are usually ideal for catching fish feeding at a particular depth below water. They usually are used when fishing in deep waters such as lakes and large ponds. The deeper the fish, the faster sinking line you should consider using.
  • Sinking tip fly line: This fly line combines the attributes of both floating and sinking lines. It allows you to catch fish that feed at some distance below the water while reducing your line’s chances of getting tangled underwater.
