How To Pick The Best Fly Line For Trout

Before you can settle on a particular fly line, consider its use. What is the intended purpose of the fly line?

Once you have an answer to that question, you are halfway through to get the best fly line. Is the fly line you are looking for an all-round one?

Are you looking for one that will cast small trout against the riverbank?

Secondly, consider the core of the fly line. The core is the skeleton of the fly line, and it gives it strength. It also determines how the fly line stretches. Fly lines for trout are multifilament, which makes them more flexible, and they stretch more.

Also, consider the coating of the line. The coating on the core is pertinent as it affects how stiff the line will be. It is also essential as it determines if the line can float or sinks. Most fly lines have polyvinyl chloride (PVC) coating.

You can make the PVC more flexible and softer by adding plasticizers. If you wish, you can use lubricants to make it more slippery.

Should You Consider The Color Of The Fly That You Want To Purchase? 

Yes, you should.  

If you are a beginner in casting, a brightly colored line would be better for you. You can see the fly line while it is on the water or in the air. The bright color also enables you to locate your line, determine whether it is dragging, and detect strikes.

Fly lines with a clear coating may be the right choice when you want to avoid spooking fish.

Also, consider the profile of the fly line. Profile refers to how the line is tapered. Tapering at the end allows for fast and farther casting while gentler tapering is for more delicate casting. The first 30ft of the line determines the weight of the fly line.

A fly line that tapers thicker at the tip is best for distance casting. One with a small diameter at the tip would be a more delicate casting.

What Are The Benefits Of Using Fly Lines For Trout?    

How would fly fishing be like if you didn't have the right fly line? Unlike other fishing, fly fishing requires the angler to use the right fly line at the right place. The weight of the fly line enables you to cast the fly line.

So, what happens when you use the wrong type of fly line for fishing? First, you will have a lot of challenges casting. Also, you may end up chasing away the fish as you struggle to cast.

It is, therefore, beneficial to have the right fly line for the purpose. With that, you have an easy time casting whether you are a beginner, intermediate, or a professional.

The main reason you went out is to fish. It will, therefore, make no sense if you end up driving the fish away. Thus, having the right fly line or trout makes it easy for you to accomplish your mission.

Attributes That Differentiate The Fly Lines For Trout

  • Fly line codes. When you want to purchase a fly line, the codes on the box can be confusing. For instance, you may get a fly line with the code WF-4-F. What in the world would the codes mean?

Simply, the codes mean the fly line has a Weight Forward Taper, 4 line weight, and it floats.

The first letters will refer to the taper, the second letters refer to the line weight, and the last letters show the density of the fly line.

  • Density. The density of the fly line refers to the fly line sinks, partially sinks, or floats.The floating fly line is the one that is widely used in trout fishing. When you want to fish for submerged nymphs, you just put weights on the leader.  
  • Color. You can also distinguish fly lines using color. For instance, colored fly lines are the best for novice fishers. Red, orange, and yellow are the most popular colors. The colors make it easy for you to see the line while fishing.

Neutral fly lines would be best when you want fish-spooking.

Brown and black are the most famous and efficient colors when you want to carry out submerged colors.

  • Taper. Taper refers to changes on the fly line that make casting better. For instance, you have the Weight-Forward Tamper.
  • Weight. The weight of the line is measured in grains, and the manufacturers give it numbers from 1 to 14. To determine the right fly line weight that you need, consider its intended purpose. Also, ensure that the line weight you choose matches the fly reel weight and the fly rod weight.

The Best Way To Use A Fly Line For Trout

Having the right fly line is one thing while making the correct task is another. 

Ever wondered why we have novice, intermediate, and professional level fishermen?

Fishing, whether floating or submerged, is an art that you need to master. If you don't have the skills, you might end up driving away the fish instead of catching them.

So, how do you make the correct cast?

While making the cast, the angler should be in a stable position to swing the cast appropriately.

If you are making a forward cast, the rod of the fly line should be straight at the beginning. You should then swing the rod forward with linear movements of your upper and lower arm and wrist.

The swing should help to drive the rod tip and line straight in the forward cast.

The swing will set the fly line in motion and give it the necessary speed.

If you are a novice, more time will be spent casting as you learn and improve your techniques. 

An easier casting line will reduce fatigue, which means you will be less tired. When you are less tired, you can make more casting which improves your skills. Your goal should be to make your casting skills proficient as you also reduce the learning curve.

When you become efficient in casting, you will enjoy a more relaxed casting motion. As such, you will spend more time enjoying your fishing experience.

Also, for the best use of the fly line, choose the right taper.

For instance, the WF (weight forward) are the most popular, and they work in almost all situations. DT (double taper) or LB (long belly) is efficient for special situations. The long belly is a practical weapon when you make long casts when it is windy. It also works well in small streams where you make short casts.

When stealth is the main mission, DT tapers are the most preferred as they have the least mass at the end of the line.

Ensure that you get a new fly line at the start of every fishing season. Get the best quality you can without minding the cost. Cost should be the least of your worries comparing the benefits the high-quality tapers will give you. A new fly line improves your casting and gives you a new casting experience.

Also, clean the fly line frequently. Cleaning the line is a major way of maintaining it.

Additionally, stretch out and smoothen the line and the leader to remove the memory coils before you go fishing. Also, avoid casting in dirty places or hard places.

You can practice casting at home more frequently so that you will have an easy time when you go fishing.

Controversies Regarding Fly Line For Trout

When it comes to trout fishing, the controversy is, "does the type of the fly matter?"

Yes, it does.

There are various types of fly lines in the market today. The lines differ in make and specifications, which is a big consideration while fishing. The type of fly line you use depends on where you want to fish.

For instance, if you want to fish in small streams, an LB (long belly) taper would be the best. It helps you make short casts.  

As such, there shouldn't be controversy anymore. The type of fly line does matter.

Safety Tips When Using A Fly Line For Trout

While fishing is a fun activity, it can be disastrous if you don't take the necessary precautions.

If you are fishing in the sea or big rivers, you should take care not to drown. Have the right protective gear and equipment. This would save your life in case the boat capsizes when there is a strong current.

Secondly, you should consider using barbless hooks in place of the barbed ones. With that, you not only protect the fish from unnecessary pain, but you also reduce the chances of injuring yourself.

Lastly, flying rods are good conductors of electricity. If you are out fishing and it starts raining, and there is lightning, consider calling it a day. You can always come back later.
