The number one professional mid-range disc. It is very reliable at the high speeds that pros throw. It ages slowly, becoming an excellent slow turning disc as it wears.
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.
The Ontario mold is my Roc of choice. I prefer the O-Roc's glide and stability over the San Marino & Rancho. The DX runs have been great lately as well, producing a nice, stout feel at 4 (or so) grams off max.
