Well now a tour may not be the same thing as extensive sampling of factory inventory before purchase...no way I'm getting a shot at that! :)
In the end we all know it when we hear it, whether it's a nice old 50s/60s/70s or one of these new lines/other manufacturers. I know I like the idea of owning and playing Zildjians, bias from youth plays a part in that. One thing I notice though, in the Kerope youtube clips, the cymbals are disappointingly too quiet compared to the drums in the mix.
