Which Roc is it, there is so many that fly differently?
They all fly different. A new Rancho feels as stable as a Pain or Hornet, New San Marino flies as straight as a Core or Buzz, and an Ontario is Flippy like a Fuse or Buzz SS. I don't throw Rocs much any more (except over the water as a disposable since I get one with almost every tournament). I agree that the rim bugs me and latitude rims don't. But I have seen some guys throw Rocs out there over 375+, with little to no fade (That make me real jealous when they do). I use my mids around or over 300 feet (power grip, snap), 250-300 (fan grip, smooth), or to glide in on a low-line no run up tree shot 150-200 (Fan Grip, slow and smooth).
