I played a few of the Rezos. Most recently, this past Saturday, I bought a new Zildjian A Custom 19" crash. While there I once again auditiomed the Rezo 19" but it did not match my other Custom As I bought with me. I also tried the A Custom Projector. To my ears the Standard A Custom had a much more full bodied sound to it.
I do like the looks of the Rezo series but the sound just didn't match up in my opinion.
