I have put a number of these onto my snare drums. They are really well made and provide a really sensitive response. I can't tell the difference between using these and the really expensive brass ones Pearl offer. What is good about these over the standard 022 snare is that they have indents where the snare string goes, so that the width of the string doesn't lift the snare away from the head, maintaining a really good response.
I have experimented over the years with most of the top of the range snares available, and I have settled on these as I can't tell the difference. Provided you tune your snare drum well, this is all you need. I would say that they do work better with a remo ambassador snare head, with the diplomat thinner snare head I found that rather than getting extra sensitivity, I got a fatter tone I wasn't really after, but that is more to do with the diplomat head than it is to do with this particular snare.
