Gene, I have a 19" Zildjian Z series I wouldn't trade gold for!!! It is one of the best I have ever heard. On the other hand I have a Rare Z series Power Crash I am trying to trade. I think it just depends on the Cymbal!!
The Z series also sound like crap to me. And you've gotta hit the hell out off it just to get that type of sound. A light studio smack and the damn thing is not even heard. Steve
