Which type of fletching provides more spin and greater in-flight stability?

Helical fletching offers enhanced spin and greater in-flight stability for arrows. This type of fletching is attached to the arrow shaft at an angle, causing the arrow to spin as it travels through the air. The increased spin stabilizes the arrow's flight, allowing for improved accuracy and consistency in hitting the target. The dynamic nature of the helical design helps counteract the effects of irregularities in the arrow shaft and flight path, ensuring a more stable trajectory.

In contrast, other types of fletching, like offset or straight fletching, may not create as much spin and thus provide less stability in flight. Flu-flu fletching, typically used for short-range shooting and designed to slow down the arrow, does not enhance flight stability to the same degree as helical fletching. Plastic fletching refers more to the material used and can be applied in various designs that may not provide the same benefits in terms of spin as helical fletching.
