The Ninja is slightly overstable with a very long glide and predictable fade. It also uses drag reducing surface technology at the leading edge to allow the disc to maintain initial launch velocity and hold rotation longer.
About the Plastic: The Diamond blend is made from a high-grade TPU. These blends create the best durability and grip on the surface of any disc on the market. Runs are clear, translucent, or opaque and are more over stable than Suregrip or Platinum.
