Hi,
As I recently got into playing heavier music, I found myself lacking volume when playing with my band. I tend to have a softer touch so I decided to buy larger size cymbals to compensate :P This 18" Classics is perfect for metal drummers as it has enough cut, great tone, and the durability / price is not to be underestimated when we all know crashes tend to break often.
The sound is great, compared to my 16" Byzance medium, it doesn't have the harshness and body, but more of the explosive high pitch and shorter sustain you would look for in a metalcore / extreme metal context.
I am already planing on buying a 17" inch medium, so I can move the 16" Byzance on the far right.
