I'll weigh in here and throw my 2 cents of bias into this discussion. I have played around with the Elite Z Buzzz and a FLX Buzzz some and have been throwing a Roc for a long, long time and think the Buzzz is less stable than a Roc. Maybe a better comparison would be comparing a Wasp to a Roc or a Shark to a Buzzz. Since the Buzzz is less stable, I don't like throwing the Buzzz into a headwind. I find a Roc or a Wasp to be better suited for that condition. Also, when I throw the Buzzz on a slight hyzer shot I do not get the same "stabling up" effect that I get when I throw a Roc. However, I find the Buzzz easy to throw and good for straight shots even when it is new and that is its strength especially for newer players. Dropping down a few grams in weight with a Roc can help get the same results when the disc is new.
i'll start by saying "to each his own". consistency reigns supreme with me. this is where discraft comes in to play. innova had great runs with CE but, in my opinion, that's it. mass production has failed. it has failed you and i and all. sure a USDGC CE Roc is money. once a year the Roc is made right, woohoo. i personally don't have the patience or the money to stock up.
i think it's all where you come from. i recently moved from kansas to colorado. It seems like i moved from Discraft country to Innova country. i'm sure it speaks true of other states as well.
Buzz is most consistent in my bag, but only FLX. A special blend Roc is close second. With so much to lose and so many cheaper options, CE isn't worth the money to throw. Makes a good trophy to hang on the wall.
we played a buzz vrs roc tourny, the overall scores were lower with the buzz but i believe the lowest score was achieved with the roc.
this tourny was in oklahoma city.
my personal preference is the buzz.
The Roc is arguably the best disc ever made, however, I like the fact that discraft offers their Buzzz in many different plastics. Even though they do make the Buzzz in a bunch of different plastics I don't think I will ever be able to walk away from my Rocs. Roc on.
