Innova's Roc is one of the most popular and talked about midranges in disc golf for a reason. It's a disc that flies extremely straight and has an excellent glide, making it an instant favorite for everyone from the pros to beginners.
At the same time, it is one of the few discs that professionals like to use in baseline plastic, as a Roc that has gotten a little itchy can almost completely lose the ability to fade at the end of its float, which is very unique and gives a huge control to those who can master exploiting it.
