Full Sink Fly Line FAQ
WHEN TO USE A FULL SINK FLY LINE?
A full sink fly line is a line that is designed to sink down into the water that you are fishing in. It is used to fish for nymphs and streamers.
Trout feed mainly below the surface of the water, so a full sink line makes a lot of sense when going for them.
A full sink line is infused with tungsten powder. This makes it heavier than a conventional fly line causing it to sink more rapidly.
Full sink lines vary in their sink rate depending on the amount of tungsten that is infused into the line.
There are a number of sink fly lines that perform somewhat differently to one another. A sink tip fly line is around 90 feet long.
The first third of this line is the sinking portion. The rest of the line will float on the surface of the water.
A mini sink tip line is between ten and fifteen feet long. It is added to the end of a floating line. Just this end portion will go under the water.
In contrast, a full sink line will completely submerge itself under the water. A full sink line is more difficult to cast than the other types of lines.
An intermediate sink line will maintain a level just below the surface of the water. This is ideal when you are working in a body of water that is full of weeds.
You can also get full sink fly lines that are slow, fast and very fast sinking.
WHY IS THE FULL SINK FLY LINE BEST FOR TROUT?
A full sink line is a good choice when you are fishing for trout because it allows you to get your fly as close as possible to the mouth of your fish.
It allows you to get the fly directly down to where the fish is located, which is something that a floating line simply cannot do.
A trout is likely to lurk on the bottom of the water and then rise to go after the fly. When the fly is at the end of a full sink line, you are able to put the temptation directly in front of the trout.
As a result, the fish doesn’t have to travel as far to take the (hopefully) fatal bite.
HOW TO FISH WITH A FULL SINK FLY LINE?
It can be challenging to cast a full sink fly line. To make it easier, you should strip the line and fly in more than you normally would when using a floating line.
You should also make a slight adjustment to your casting stroke. In addition, opening up the casting range of motion will also help. Try to make just a single back cast.
Which type of sinking fly line will perform for your needs will depend on what type of water and which species of fish you are after.
We offer a our top choices and explore their strengths and weaknesses.
Before you select a sinking fly line you need to know what application you are going for.
Sinking fly lines are made to sink at a specific rate that is given in inches per second, and is abbreviated ips.
Obviously you don’t want to fish a fast sinking line in water that is too shallow, because you’ll snag bottom.
But the most important deciding factor in selecting a full sink fly line is at what depth you expect to find the fish feeding.
Casting fast sinking line in relatively shallow water will require a faster retrieve. But if a fast retrieve is what you are after, then a fast sinking line might be the answer.
But if you need to retrieve slowly, or even pause frequently during the retrieve then you will want a slower sinking line.
And if the water is really shallow then maybe you even should consider an intermediate line, which sinks around 1-2 inches per second.
Type III and IV sinking lines are good middle-of-the-road sinking fly lines, which sink at a rate around 3-5 inches per second.
Most anglers find type III and IV provide for a good range of fishing depths while still allowing good control.
For top performance and the best chance of success, it is super important that you use sinking fly line for the correct application.
