I'm on the range Z custom rock for over six years (charles, ride 21 "crash from 16 to 19"), I find that in recent years of the alloy cymbals and a lot less tough than before. It is a scandal, I have to change the set every 4 to 6 months. I do not play in a metal band, I use real wooden tub, and I'm rather careful.
I therefore strongly recommend the choice of this series, considering the price ...
However, the sound of these cymbals are powerful and hot.

I now play on a set sabian MetalX, ca seems to take a little longer.
