The lines have evolved a lot and conventional tanza is already out of fashion. Monofilaments and multifilaments are increasingly a viable option and have more and more advances and advantages. Then the pro and contra of both.
The lines with multifilaments are composed of several strands twisted, have no elasticity or memory, but are very resistant to abrasion. These are not transparent, they do not resist rubbing against the rocks and given their lack of elasticity (which can produce a break when there is a dry pull), it is advisable to use a monofilament (or common line) of approximately 1 or 2 meters at the end of line.
The multifilament lines are more resistant than the common lines with equal thickness, and therefore when using lines with a smaller thickness we will make longer launches. In the case of fishing with rod, it is advisable, that the rings of this type are SIC if we want to use the lines with multifilaments.
As it is not "stretched" when topping, do it more slowly than when we use common nylon so as not to break the fish's mouth if it is caught or any part of our equipment.
Finally, when using multifilament lures go deeper.
As we have said are most of the current polyesters, consisting of a single polyester filament, (although some are coated with different "elements" to give them one or other properties like Aluminum, Titanium, with textures to favor the generation of effects, etc. ...) and its most characteristic properties are:
IN FAVOR: Durability, generation of effects, greater sense of control; Do not move the strings; Most affordable price. In addition, on windy days the multifilament flies too much thus, dragging the lines. They have greater elasticity than multifilament and great resistance to abrasion.
AGAINST: Loss of tension, comfort and touch reduced, high "stiffness" which is harmful if you have problems in the elbow.
