I've tried the Z3's and they were pretty nice if you get them Im sure you'll be happy. But im more of a
sabian guy so i would recommend you look at
sabians AAX and HHX line they have some great cymbals in those line. It sounds like you might really like the AAX fast crashes. They are thin and have a great sound. Heres a video of mine that i posted on youtube.
Also if you are worried about the quality of
sabian cymbals for any reason all their high-end cymbals are hand checked for sound quality up to 3 times before they leave the factory. Also they have a 2 year warranty.
