As with any cymbal set-up, your match of ride, crashes, and high hats; are a personal matter. If you can hear in your head what you need, then don´t give up until you have found the right sounds. Believe me, it takes years to find your own personal sounds. The 20" K Constantinople that I found, fit to my other cymbals perfectly; naturally also vintage Zildjian cymbals. I must say that it only could be Zildjian that I would play. Still I have many rides, crashes, and high hats in my collection; just waiting to be combined for other playing situations. I have been playing music for more than 50 years, I will still grow, as long as my ears work.
This also means that my Zildjian collection will peobably also grow. Drum crazy? Yes I am! I live to play Music! I play music to Live!
