So far am loving this. Have bought for a church kit, where we want a warm, mellow sound to the whole kit. Have replaced a pair of 14" Zultan Caz hats (which are excellent) with a pair of 16" crashes (Zultan Caz as bottom hat, this CS as top hat) and it's dropped the fundamental pitch of the hat substantially .. which is partly just the size change of course .. but given it a warmer, dryer tone too. This is not a setup for hard hitters, but has done exactly what I hoped. Didn't play it much as a straight crash, but what I did, I loved it for that too. Would use it very happily as a crash, particularly for jazz.
So far my experience with the CS series is very positive. The Caz are incredible value: the CS are worth the bit extra.
Footnote. Have bought cymbals from Thomann several times now and their packing has been an issue. This time round their packaging department had clearly upped their game. A very welcome change.
