L-Style EZ dart flights are the rendition of the Pro flight with a built-in Pro ring and a softer and smoother surface. It keeps all the benefits of regular pro flights but is a little softer for reduced deflection.They have a Perfect 90 degree angle for an accurate throw, weigh the same as a standard flight and are made from a soft and flexible material that can easily bend for adjusting. They are easy to fit onto your shafts and compatible with nylon and poly shafts only. Because they are not laminated, they have a longer durability.EZ flights can ONLY be used with nylon or poly shafts.
