For hard rock. I use a Sabian
Rock Ride. It's a 22 inch. I bought it in 1985 sometime. Lots of ping, a good bell, and you can still build up some wash with the shoulder of the stick without completely losing definition when using the tip.
version is basically identical.
I saw a Z3 one with a big bell recently that really impressed me.
I prefer medium weight crash cymbals myself. I have an 18" Paiste
2002 crash (not the one they call medium, which is actually a little heavier than medium), a 17" Zildjian
Z3 medium crash and an 18" A. Zildjian
