The legend of the Viking Raven is this. Two Ravens named Huginn and Munnin sit on Norse God Odin's shoulders. He sends them out to fly over the world at dawn; they return and tell him everything they hear and see. This flight is hand-drawn by the Shot design team. Vikings used the Raven symbol to strike fear into their enemies in battle.
Slim flights are ideal for players using lighter darts. Or, if you simply want a flatter trajectory of your darts and are used to a standard flight, this flight shape may work for you.
