Leaders

Since a fly line is so thick and visible, you don't tie the fly directly to it. Instead, you must use a leader, which is comprised of different diameter monofilament or fluorocarbon lines. Using a leader not only allows you to tie on the fly but also lets the fly be presented in the most natural manner possible. Unfortunately, there is no ONE leader for all species and situations, so you must tailor the configuration to your specific fishing. 

Turnover

A leader is typically tapered; it starts thick and ends thin. Leaders can be purchased knotless or constructed using different lines tied together in a specific order to form the taper. Along with a good cast, the right leader will propel the fly away from the end of the fly line. Having this proper "turnover" is important for getting a solid presentation.

The fly's size and the leader's stiffness will impact the ease of turnover. A long leader tapering to a supple tippet may be perfect for presenting a tiny #18 dry fly in a quiet creek, but it will lack the energy and stiffness for tossing a much bulkier fly. A stiffer, shorter leader will transfer energy from the fly line more effectively for better turnover of larger flies.

 

Sections of a Tapered Leader

Butt: This is the only section directly joined to the fly line. The butt section is the thickest portion of the leader and is usually made from a stiff line with about the same stiffness as the fly line. One key point to remember is that turnover power increases as the length of the butt section increases. At the same time, too short of a butt section in relation to the midsection and tippet may not provide proper turnover power for heavy flies.

Midsection: The midsection is the middle of the leader and helps transfer energy from the stiff, thick butt portion to the more supple, thinner tippet. A long midsection and/or tippet can help provide a softer presentation and more natural drifts.

 

Tippet: This is the thinnest end of the leader where the fly is tied on.

 

Overall Lengths/Tapers

A few variables come into play here, including the type of fly line being used and the size of the fly. Leaders can commonly range from just a few feet to well over 10 feet, but a length around 9 feet is a common starting point for many situations with a floating line. With sinking fly lines, leaders are typically on the shorter end of the spectrum for two reasons: a shorter leader allows the sinking fly line to pull the fly down faster, and sinking lines usually have naturally-colored sinking portions that likely won't spook fish as readily.

 

As mentioned earlier, a tapered leader has a gradual transition of diameter/poundage/stiffness throughout its taper. Folks make them in many combinations, but an old baseline formula is the 60/20/20 rule. This means you'd use a butt section that's 60% of the length of the entire leader, followed by 20% midsection and 20% tippet lengths. To briefly model this formula, the following is a basic example of a 10-foot leader and its corresponding (diameters) in inches:

 

Butt Section: 6 feet of 25-pound line (0.024") 

Midsection: 2 feet of 20-pound line (0.021")

Tippet: 2 feet of 16-pound line (0.018")

Despite the simplistic example, the leader is often constructed not just with different overall lengths and varying section lengths, but it may also use more pieces of line per section, as shown above. The leader will still have the three main sections, but more than one piece of line will be used per section to achieve the gradual, progressive taper down to the tippet. This can be especially common if trying to create a taper down to a fine diameter tippet. With these delicate leaders, presentation and knot strength can suffer if the difference in diameter between each piece is too great, so extra pieces are used to keep the taper more gradual. 

A final tip is to try using the same brand/style of line for each piece in your leader. Since different manufacturers' lines can all have varying stiffness and diameters, using the same line type along the entire leader ensures each component works together fluidly. Tying a leader like this can be quite a chore, but knotless leaders provide an excellent alternative.

X-Rated

Tippet materials are labeled by their breaking strength in pounds, and some also carry a numerical "X-rating" on the package based on the diameter. Packaged tapered leaders will also show this X-rating to represent the tippet diameter used in the leader. Below is a breakdown of common X-ratings and their equivalent diameters (in inches).

0X = 0.011

1X = 0.010

2X = 0.009

3X = 0.008

4X = 0.007

5X = 0.006

6X = 0.005

7X = 0.004

8X = 0.003

Additional Notes:

- Each time the X-rating goes up, the diameter decreases by 0.001. 

 

- A fast way to determine diameter is to minus the X-rating from where the scale begins at 0.011. So, a 7X tippet is 0.004 in diameter because 11-7=4.

- Heavier/thicker tippets (like those commonly used in salt water) are often just referred to by their breaking strength rather than an X-rating.

- The X-rating of a specific tippet size won't always be rated at the same poundage. For instance, a 4X tippet from a particular series may be weaker than the 4X tippet of a different series from the same or another manufacturer.

Knotless Leaders

Aside from constructing your own leaders, knotless leaders are convenient options. These one-piece leaders are already tapered, so there's no wasted time tying knots and thus no extra knots to hang up in your rod guides or get fouled by debris. A spare tippet spool or two is good to carry, though. Knotless leaders only have so much tippet portion built-in, and after you change flies a bunch of times, the tippet gets too short. In many cases, it's even a good idea to add on a length of your own tippet to the end of the leader before the first cast is made. This gives you more tippet to play with and makes for better drifts with small flies.

Nylon Monofilament vs. Fluorocarbon

Standard nylon monofilament is generally cheaper than fluorocarbon, but it works fine in many instances if you choose the line size correctly. That said, fluorocarbon is often touted to offer advantages like added durability, less stretch, and less visibility to the fish, making it very popular. Fluorocarbon also sinks slightly faster than regular monofilament, which can be a good thing depending on where and how you're fishing.
