This Package offers two sets of the most popular shaft sizes in the dart community. 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. When using an aluminum shaft, o-rings are strongly suggested.
