This cymbal is a great addition to any kit where you want washy, right-side alternative to a open hi-hat in the rock songs. I use it a lot in the situation where I want to bring more energy to the chorus/bridge and I'm not there yet to rock the heck out of the crashes.
Sounds a lot like smaller and lighter china cymbal, but unlike china this one sounds more "stereo-spreaded" as it is occupies most of the room. It is loud.
I personally dig Custom Dark series so much, so take my opinion with the grain of salt. These series are perfect for medium and big stages. To much volume for small stages - I've tried.
