The 21" Impression in my playlist has two rivets by now. You hardly notice them in the soundfile, but they add some high end sparkle to an otherwise rather dry sounding cymbal. You can still hear the beat. That's the thing: the stick definition/rhythm of the ride should always be clear.Sizzle or rivets on the main ride acceptable ?
That said, I'd like to reiterate: big bands playing is not about "cutting through". Nobody in the band wants that. It should be a sound that doesn't fight the other instruments, rather complements them.
