I've got an ace on a buzzz and hated the Roc for years. It seemed everyone threw the Roc and I was not going to foolow that trend. Well, needless to say, I have been babtised into the world of the Roc. Now I prefer mine to be "flat top" 180 weight. But these things, with a fluid throw (not just a crank) are laser straight and will not let you down. I do not like the KC Pro (regualr stamp) Rocs as these are too domey. BUt, it really depends on what you like and what suits your game!!
