Just upgraded my Zildjian ZBT cymbals with Zildjian K Custom Dark. It's like going from getting a lap dance from the ugliest girl at a bargain basement strip club to banging the prom queen! Technically, I've never done either of those things, but you get the point. I used to dread hitting the cymbals, especially that tinny sounding ride. I bought the pack that contains a 14" hi-hat pair, 16" and 18" crashes, and 20" ride. My old cymbals (that came with the entry level Pearl SoundCheck kit) were a 13" hi-hat pair, 14" crash, and 18" ride. I've ordered another cymbal stand to hold the additional crash cymbal. Already finding that I want to practice longer! I highly recommend the K Custom Darks!!!
