Links are classified according to the international AFTM system (Associated Fishing Tackle Manufacturers) based on taking into account the initial weights 10 yards (9,14 m) links. Sequential numbers in Arabic numerals from 1 do 12 (the classification of the rods is also consistent with this) denotes cables with unified weights, e.g.. the lightest is the line no 1 (9,14 m = 3,9 g), the heaviest no 12 (24,7 g). Two basic factors determine the value of fly lines:
– behavior in water i
Depending on the first of them, the following types are distinguished:
– flying (F – Floating Line);
– sinking (S – Sinking Line);
– indirect (I – Intermediate Line);
– floating with sinking tip (SF – Sinking-Floating Line).
Due to the shape, we distinguish:
- cylindrical (equal diameter from start to finish; L – Level);
- necessary (symmetrically tapering towards both ends; DT – Double Taper);
- one-sidedly necessary (ST – Single Taper, Shooting Taper);
- necessary overloaded (asymmetrically tapering towards both ends; WF – Weight Forward).
• Cylindrical lines are simple and cheap, however, they can only be used with imprecise fishing. Their advantage is this, that, depending on the needs, they can be shortened and it does not change their class (number).
• For practical reasons, horse links are among the best, which are easy to throw thanks to their weight and low air resistance, and especially because of this, that they can be used from both ends. They are manufactured in AFTM numbers 4-12.
• One-sided conical ropes are also thrown very well and accurately, thanks to their quick submersion, they are especially suitable for nymph fishing.
• Horse lines overloaded are suitable for all fly fishing methods, however, they lose their usefulness as the ends wear out.
The currently produced lines have a lagging and core structure. Depending on the type of core, we distinguish between lines:
– with a single-fiber core (most often in the form of a fishing line) covered with a lagging;
- with a multi-fiber core (the core is a weave of fibers).
Monofilament core links, easier to manufacture, are correspondingly cheaper, however, the hooklink cannot be attached to them with the end eyelet (Action), and sometimes – due to the thick core – they are characterized by "shape memory”. Links with a multi-fiber core are qualitatively better, therefore and correspondingly more expensive. The surface finish of both types of lines is equally precise, so that you can throw the line lightly.
The color of the line has practically no effect on the effect of fishing – if only that is why, that you are using a relatively long line leader. Some experiments show that fish are not disturbed by even the brightest colors, so the choice of the line color will depend on the personal preferences of the angler. However, if it is necessary to adapt the cable to the environment, choose clear lines from among floating lines (sand gray, White, orange), while sinking lines should be rather dark (Brown, green, grey).
Rope packaging labels are provided with comprehensive characteristics that take into account the basic properties of the product, they must be fully respected. First of all, it is necessary to match the line to a specific fly rod (and conversely).
