I've got a paiste setup, and i love it. Great for heavy rock style stuff (got a mix of 2002 and 602 crashes). If i wanted something a bit lighter, a 16 and an 18 A custom is what I'd go for.
I've got a great Z Custom Ride, but Z crashes have always been too heavy and "raaaawr" for my liking
mate, do us all a favour. go to your nearest cymbal stockist and try some out. its the BEST way to find what you want. No amount of forum discussion will give you the definitive answers.
