Several pieces of equipment are used in the sport of fly fishing. One of these is the fly line. It is the piece which is cast in fly fishing since the flies used in this method of angling are virtually weightless.
Modern-day fly lines are made of a tough braided or a monofilament core which is wrapped in a thick layer of plastic. They also come in a variety of models which are used in different kinds of environments.
There are lines that can be used in seawater then there are those that can be used in cold temperatures. Each specific model ensures maximum effectiveness when used in the environment it was designed for.
Fly lines come in different sizes. These sizes are not only important in buying lines but also in determining the rods they can be used with. It is because a lines size is always matched with the weight of the rod. So for example, a #7 line is to be used with a rod of 7wt.
Aside from the line, another consideration when buying a line is the taper. Some lines have a taper at one end while others are tapered on both ends.
The advantage of the latter over single-tapered lines is that the other side can still be used when the other one is worn out.
Also, the taper has an influence on how well it can be cast. A heavier taper can be cast easier which is why it is recommended for beginners.
