I've used this cymbal off and on for a while now. Everything from the K Custom series are well-made cymbals and sound wise are a cut above your average cymbal, but the K Custom Dry Ride stands out as a great choice (if it fits your prejudices in a ride cymbal). What I like most about it is its complexity, like a fine wine. This is probably the best dry ride I've ever played, because most dry rides are too dry and bland but not this one. This cymbal IS pretty dry, but it still has some "sizzle" too it, which give it a smoky sound and dark overtones. Its mellow but not wimpy, with a very defined "ping" and a subtle shimmer underneath it. Being a dry ride, of course, it has minimal sustain but riding it hard to try and build up some "wash" and "shimmer" underneath will leave you pleasantly suprised. Its all in how you play this cymbal.
I doubt that I would play this cymbal in a very agressive rock band, but I suppose you could if you wanted to. Being a dry ride and as dark as it is, I doubt I would use it in a jazz or fusion setting either. I think the perfect situation for using this cymbal would be a progressive rock band, or a more mellower rock band where you demand some complexity in the tone of your cymbals, and still want it to cut through.
Everything in the K Custom line is going to cost you some green, but if you are looking in this price range for cymbals then you must be discriminating enough to pay K Custom prices. I doubt you would be disapointed. I don't think Sabian or even my beloved Paiste makes a dry ride to compete with this one.
