I think I read this right:
Nuke
TB
Buzzz/Roc
Aviar
that's actually a solid setup that can accomplish pretty much anything.
The only thing I would say you might want to try is some kind of flippy disc and or a lid like disc. Flippy disc I recommend a DX Stingray, DX Leopard, Mamba or Avenger SS. Lids I recommend are Sonic, Polecat, Rattler, and Bite.
Other than that you really aren't missing anything.
I loved my Nukes. Farthest disc I've ever thrown. Especially once I beat the hell out of them. Nice and flippy! May have to get one again!
