This Package offers two sets of the most popular shaft sizes in the dart community. Many players prefer a nylon shaft because it does not bend. Nylon shafts can be part of a shaft/flight system that includes stem rings (search ASIN B00DQDA53U). In order to insert the stem ring in to the flight, the flight must be punched with a flight punch (search ASIN B00DQD6QL0). Sizes of shafts are not just for the preference of the user. Shafts come in many lengths for a purpose, and that purpose depends on how the dart is thrown. A Softer toss generally requires a longer shaft and a larger sized flight. Conversely, the harder a dart is thrown, the shorter the shaft and smaller the flight should be.
