Replace your line regularly

Replace your old fly line so “the fish of the day” doesn’t become “the one that got away.” Your six-pound tippet & leader from last year is probably about as strong as 2-pound tippet this year. Fly fishermen should check their fly line for cracks and replace leaders and tippet regularly.


 Our  range of knotless tapered leaders are designed  for better turnover power and the supple front taper ensures delicate presentation. These knotless tapered leaders are an excellent choice for fishing with the small or mid sized flies used in the United Kingdom and North American streams and rivers. They are ideal for casting to easily spooked fish and are  offered in  9 foot, 12 and 15 foot lengths.

Prices are:

9 foot tapered leaders 0X -6X                All Sizes £2.99

12 foot tapered leaders 0X - 6X             All Sizes £3.25

15 foot tapered leaders 0X - 6X             All Sizes £3.50

The Fly Line

The fly line is crucial: having the right line for your rod and the type of fishing you do can make all the difference between a pleasant day of fishing and utter frustration.

Floating Fly Line vs. Sinking Fly Line

Fly lines are made of different materials that perform in markedly varying ways. They’re coded using different letters.
  • Floating (F): These lines are made from a braided line (We do not use poly core due to its memory problems) covered with a PVC coating: the coating contains tiny micro balloons that make the line lighter than water so it floats. Weight Forward Floating Fly Lines are popular among beginners because they’re easy to cast and can be used in most situations.
  • Intermediate (I): If a floatant is applied, these lines float. If not, they sink slowly at about 1" per second.
  • Sinking (S): These lines are usually made with a coating over a hollow, braided nylon core. Different coating materials have different weights: the heavier a line compared to water, the faster it sinks. Sink rates for these lines range from about 2–10" per second.
  • Specialist Midge-tip and Buzzer lines (F/S): These lines are floating fly lines with a black tapered tip portion that sinks. Midge Tip Line was created to fish nymphs and buzzers sub-surface and down to 8foot within which parameters most lake fish are caught. Our Midge Tip & Buzzer Floating Fly line terminates in a 12 ft black sinking section with a built in welded loop. This longer front section not only gets your fleis down to the fish faster but, also allows the use of shorter leaders which reduces line "belly" and missed takes.

Line Weight

Fly lines also vary significantly by weight. This table shows the American Fishing Tackle Manufacturing Asso­ciation (AFTMA)’s mea­sure­ment system, which categorizes lines from 1 (lightest) to 12 (heaviest). Weight measurements are rarely exact, so the table gives a range of acceptable weights for each category.
Most beginning fly fishermen use line weights of 5–7, which are very versatile on both still water and rivers. The lightest lines (1–4) are used for much more subtle presentations. Heavier lines (8–9) are sometimes used for choppier and windier conditions but in truth a lighter line is far better in these circumstances. If you use a 7 weight rod then in windy conditions use a 6 weight line but let out about 40 foot or so in order that the extra line fully loads your rod. Keep your heavier lines for larger flies and bass bugs. The heaviest lines (10–12) are used for saltwater fishing but even here many experienced angles have discovered that the lighter your line weight the more chance you have of catching fish.


The diameter of every fly line gets narrower toward the front tip. This taper dissipates the force of the fisherman’s cast as it transfers to the leader and fly, which lets the fisherman deliver the fly delicately rather than just slap it forcefully onto the water. The most common fly line tapers appear below. There are many others, but they are all variations on the weight-forward taper or shooting taper.

Weight-forward taper (WF): In this line, weight is concentrated in the forward section, so the heavy line can pull the lighter running line for extra-long casts.

Double taper (DT): This line has an identical taper at each end. A double taper line is easy to cast with delicacy and also easy to roll-cast. Moreover, both ends can be used if the line is reversed, thus giving longer life to the line. However, it does not cast long distances as well as a weight-forward line.

Bass taper (BT): This is a weight-forward line with a short front taper to cast large, wind-resistant bass flies. It lacks the delicacy needed for fishing dry flies. Shooting taper (ST): This line consists of a 30–40' head with a factory-spliced loop for attaching monofilament or running line. It’s useful when casting large sinking flies in rivers for salmon and steelhead, but since it doesn’t allow a delicate presentation, it isn’t recommended for other types of fishing.

Level taper (L): This line is inexpensive but doesn’t provide a gradual release of force to leader and fly, and isn’t available in all line sizes, so it’s not recommended.

How Fly Lines Are Labelled

Every fly line you see on a store shelf will have an alphanumeric code on the box. For example, you might see “WF6S,” which indicates a weight-forward, 6-weight, sinking line. Or you might see a “DT4F,” a double-taper, 4-weight, floating line. The first line might be useful for fishing large sinking flies, while the second might be the choice for fishing small floating flies. However, you always need to match the weight of the line to the rod you’ll be using.


More specialized lines cost more. For instance, if you need more delicacy in casting, you’ll want a line with a longer front taper and/or a thinner profile. If you need more distance, you might want a self-lubricating line. For any line other than the most basic, expect to pay more.

What Kind of Line Should You Buy?

The right line for you depends on the type of fish you plan to fish for, the type of water you plan to fish in, and the type of fly you plan to use.

To catch trout (in small to medium rivers), bass (in ponds or streams), or panfish (in any type of water): Try a WF3 - 6F fly lines. They cast flies from sizes 2–28 well  and the floating line allows easy pickup as you start your back cast.

To catch bass with bass bugs or streamers: Try a bass bug taper, also WF6F but with a short front taper.

To catch northern pike,  steelhead, or salmon: Get a 7 to  8-weight rod and WF7 or 8F line. These fish take large flies that cast better with the heavier line and they also require a heavier rod to fight them. Genwair Fly Line BoxGenwair Fly Line

Whatever line you buy, always wind some backing on the fly reel before the line. Backing is a strong line, usually made of braided, 20- to 30-pound test Dacron® (“pound test” indicates the line’s breaking strength). The backing’s thickness increases your reel’s arbour diameter—the diameter of spool that the line winds onto (or unwinds from). This makes it quicker and easier to reel in long lengths of line and keeps your line from forming tight coils. Remember not all fly lines are the same! Mill end line is exactly that the end of a run. Cheaper lines tend to be thicker and not as slick. They are also unlikely to carry any guarantee and could  in the long run cost you far more than a more expensive high quality line. At Genwair we try to provide top quality fly line at the best possible price. Genwair fly lines are covered by our 2 year guarantee.
