From the Manufacturer...
The Rhyno is an overstable putt and approach disc that can handle headwinds. Great for players with lots of throwing power as the Rhyno stops on a dime and stays close to the basket. It is a must have disc for short to medium up shots and putting into the wind. The R-Pro model is also called a “Soft” Rhyno and is made to be super soft and flexible in an extra grippy plastic that grabs the chains.
