As you can tell I am a
sabian man

always try out want your buying before you buy it cymbals are tricky things to buy
Also buying cymbals individually is the best route, you can match the cymbals up yourself in the store and make your own set of cymbals unique to your setup. I'm currently in the process of doing this.
