Gotta say the 2002 18in crash sounded really nice (I'm a
sabian guy). From what I read on the cymbal it's made of a b8 alloy which would be the same as a B8 pro cymbal from
sabian. The price tag is also nice compared to the signature series ( $115.32 difference in USD). If it was me I would go for the 2002's. Sound great and a little bit more affordable. It's all personal preference, so it's all on you. Sorry I couldn't help more about the crack in your cymbal. All in all if they're gonna replace it for free I'd say give it another try and then after that go for the 2002 series. I really couldn't find much on your 802 series crash.
