Fly Fishing Lines for trout
There are several types of Fly lines. I will only cover a few of the most common here. Fly fishing lines can have a significant variance in price. They start at around 10$ and go all the way up to $100. Fly fishing line is not something you should go too cheap on. There are a lot of good lines in the 40-50$ range. I would advise you to go with them over the cheap ones. Do yourself a favor and don’t go to a big box store and buy the cheap junk. There is a big difference in quality, and casting. If you try to learn to fly fish with inferior lines and equipment you could easily get frustrated. Catching brown trout is tricky business. Its important that you can cast to the best of your ability. This simply cannot be done with low quality fly fishing line.
Weight Forward Line
Weight forward line has a very thin back end and becomes larger and heavier towards the front end of the fly line. This allows you to cast longer distances and will be easier to learn to cast with than some of the others. This is especially good for windy conditions and fishing larger water where longer casts might be in order.
Double taper fly fishing line is just as the name suggests, double tapered. Each end of the line is tapered down, with a very thick midsection. This is good line for smaller streams. It’s tapered design allows you to make gentle presentations to easily spooked fish. For shorter casting distances, and a slightly more advanced caster this is a good line choice. This line will not “load” the rod as much on shorter casts and tends to make beginners struggle with casting it.
Sink tip fly fishing line has a floating body and midsection with a sinking tip. This is a good choice for some areas such as lakes and in certain conditions in rivers. An example of where you might need to get your flies down to the fish quickly would be streamer fishing. On some days it is best to get your flies down to where the fish are. There are different wights of tips for sinking fly lines. They all sink at different rates and are labeled as such. The deeper you want to get down to, or the faster the water is, the higher the sink rate line you should purchase. There are also full sink lines available. They are for mainly fishing deep lakes. These are very heavy lines and tend to be difficult for beginners to get accustomed to.
Full Sinking Lines
Full sinking fly lines can take some getting used to for new casters. These lines are extremely heavy and difficult to cast for all but the most experience fly fisherman. The full sink line is ideal for casting to fish that are deep in the water column in lakes and deeper rivers. If you need to get your flies down quickly this is the best choice.
