I can help you out there. I have 2 extra cryztal z Buzzzs as well as another 20 buzzzs of all shapes and sizes. I can send one of those cryztal ones your way, and Ill look through the rest of my discs before doing that to see if theres anything else discraft that might do good by you. The Buzzz outdoes the Roc and Core. Of course thats just my opinion. Ive got a few sweet special Buzzzes in my bag too. Not too shabby.
