I find that 602 cymbals sound great with or without damage. I can confidently say that if the crack gets worse, it will still sound like a 602 cymbal with a slightly different character. At least that's been my experience. I own 3 Formula 602 Sound Edge tops that have one crack each. I bought them that way and got good deals because of it. I also have a few that are in perfect shape. I can pretty much guarantee that no one listening in the audience or on a recording would know if the drummer is playing a cracked top cymbal or not. That being said, however, I, or someone else, may eventually repair my cracked tops. But for now, they sound great regardless of the cracks.
