ah okay thanks kala ko kasi mga k's ang katunog hehe
I second your opinion. I also believe that Paiste twentys are much more comparable to K or K customs as they are both made from B20 alloy and hand hammered. Actually K and K customs are machine hammered but controlled by a computer to do random hammering hence to simulate "hand hammering." A and A customs are machine hammered and hammering marks are arranged in a certain pattern to produce brighter sounds.
Having tried Paiste and Zildjians side by side, I can say that they are very much different, as each brand is made in a certain way. They may be close but there are still some unique character in them that differentiate them from each other.
