Here's what Innova has to say about the Roc:
The Roc is simply the best, most versatile mid-range disc ever made. It provides accuracy at any range. This disc can take and hold the angle of release, even into a headwind. It can be used for driving, upshots, straight shots, hyzer shots or anhyzers. The Roc ages gradually and predictably. If you’re not sure what disc to throw, choose the Roc; just like most pros.
