The Rhyno is a popular slow flying overstable putter with very little glide. This disc features a Thumbtac groove that helps provide excellent grip and controlled shots. The overstable nature of this disc makes it good for headwinds and short drives where you don’t want to overshoot the basket. 2/1/0/3. DX is an inexpensive, basic plastic. It has good grip, but wears more easily than premium plastics.
