From the Manufacturer...
The Stingray is a large diameter disc that has a very predictable turn and excellent glide. It has a shallow rim that makes it easy to grip for smaller hands and allows for a smooth consistent release. These characteristics make it a good choice for beginners. The Stingray is also an excellent disc for throwing controllable mid to long range roller shots.
