I was disappointed with these. I chose them from the sound file, as they sounded like they really sustained, but in reality they don't, despite being really quite heavy. They would be more suited to fast playing, where the sustain is not such an issue, but for the gentle chanting type atmosphere they are not that brilliant. Maybe I am being harsh, as I bought these to replace a really superb pair I had, but since I have bought a Sabian pair which are much more to my liking, and in the same price point.
What I would say in their favour is that they do offer 2 completely distinct sounds, you can tap the edge of one against the bell of the other and you get a totally different pitch and tone to hitting both edges together, which is something which you don't get from other pairs.
