With this set you get four high-quality, brilliant b20 cymbals for the price of 2 or 3... So you can't go wrong.
But be aware that these are heavy cymbals. Especially the ride is not suitable for small rehearsal spaces or band practice. To my ears it is the classic heavy metal sound.
The crashes are more versatile than the ride, but they are still heavy and don't open up easily. But they have a full sound and good separation between them.
The hihat was a pleasant surprise, I was reluctant at first because sabian does not offer this hihat outside this pack, but for me it was the best of all the cymbals in terms of all-around usability. A classic high-pitched rock sound, without being overpowering. When played closed with the stick, its definition invites you to play funk and 16th-note patterns. A great all-arounder.
Buy these cymbals if you play hard rock / heavy metal or if you already own lighter ones and need something for the stage.
