Der Trommler, you DO know that
Paiste uses B8 for 2002, right? There's lots of amazing B8 cymbals.
And B8, B12, and B20 are the most common, and they could very well be the only types of cymbal bronze alloy; I've never seen anything else. B8 is technically and sonically "worse" than the rest, but many other factors, like lathing, bow slope, hammering, and bell size contribute to the sound and sound quality.
