Yeah, not well loved, not well reviewed. May do better splitting them up.
As for the cab having Vint 30s in it....nah, don't think so. Not stock, anyway. Usually they have Celestion's bulk sales drivers in them.
Hells yeah! The Naz was an early influence of mine. I recently started working on a cover of Razamanaz...kind of a tribute to my uncle who really helped me get into playing way back. Maybe I'll finish it someday.
