Fly casting running lines, also known as shooting lines, are an essential component of a fly fishing shooting-head setup. They are thin, specialised "slick" shooting line that connects the shooting head to the fly line backing. The purpose of a running line is to offer low resistance from the angler's casting stroke to the shooting head, allowing for longer and more efficient casts.
When considering a purchase of a fly fishing running line, several key features should be taken into account. Firstly, the material used in the construction of the running line plays a crucial role. Common materials include monofilament, braided nylon and coated PVC or polyurethane. Each material offers distinct characteristics in terms of durability, slickness and handling.
The diameter of the running line is another important factor to consider. Thinner lines tend to shoot through the guides more effortlessly, resulting in increased casting distance. However, thicker lines may offer better handling and control, particularly in adverse weather conditions or when wearing gloves.
The slickness of a running line's surface is also a significant consideration. A smooth and slick coating allows the line to slide through the fly rod guides with minimal friction, maximising casting distance. Additionally, thicker lines are less prone to tangles and knots, enhancing overall performance and ease of use.
Another aspect to evaluate is the visibility of the running line. Depending on the angler's preference and fishing conditions, running lines are available in various colours, including high-visibility options. A highly visible line can be advantageous for tracking the line's movement during the cast, facilitating mending and line management or the water.
Furthermore, the length of the running line is worth considering. Longer lines provide greater shooting distance, making them suitable for long-distance casting or situations where additional line is needed to reach distance.
Lastly, the memory and tangle resistance of a running line are important factors to assess. Lines with minimal memory are less likely to coil or tangle during casting, resulting in smoother and more efficient line management. This characteristic becomes particularly relevant when making repeated casts or when dealing with colder temperatures that may increase line stiffness. Mono running lines offer the best shootability but can be more tricky to manage without tangles.
In conclusion, when purchasing a fly casting running line or shooting line, it is essential to consider factors such as the material, diameter, slickness, visibility, length and tangle resistance. Balancing these features based on individual fishing preferences and conditions can lead to an optimal shooting head setup that enhances casting performance and overall fly fishing experience.
