Decide what you want the cymbal for first, what style of music, what nuances you need for your music i.e loud, soft, full, explosive, long or short sustain, size, etc.
Then look at the
Zildjian site and narrow down a series and listen to sound files to get an idea. Use your ears as to what fancies you and will fit into your music that you play, forget about glossy brochures and cymbal appearance (or what any other drummer uses unless you can try and find the same cymbal which is likely to be a bit different anyway).
Bottom line is do some research and discover your instrument in the process.
