I have never been a real fan of the china cymbal, although I do own one. Its nothing special, just a 20" Wuhan, bought it because it was cheap and to have in the cymbal arsenal.
However, there are only two guys I've ever seen play a china where I liked what I heard.......Billy Cobham's Zildjian swish cymbal on the Spectrum album, and Jack DeJonnette's china that he used with Sonny Rollins on the 1981 Montreal show....I think that that one was determined to be a Paiste Sound Creation china......if all china cymbals sounded like either of those, I'd be sold on them. Unfortunately, most sound like garbage can lids when you hit them....the one I own included.....
