I went to a "left-side" ride when I bought "The Beast" from TomCat on this forum.
I took my old 20" Z and mounted it to the left and I end up using it a lot....very convenient position for me anyway. Then I used TomCat's 22" on the right....it has more ping and the 20" has more wash so I have some variety and they do seem to compliment each other.
Both are older cymbals....I've had the 20 for over 40 years and Tomcat had the beast for 25 years.
