The ZBTs rock! I've got a pair of hats and a crash/ride from them, and in comparison to my A Custom Crash, it was hard to find a quality difference. The hi hats were open and dark, like
Paiste Dark Energies, but crisp, sharp, and bright, like... like
Sabian AAXs. I love them. The ride on the ZBT crash/ride is horrible, but I never use it for that anyway.
