So I have this zildjian ride that came with my 1st drum set about 20 years ago. It is the only cymbal that I've never had to replace and it is a signature of my sound. It had some keyjoling when I got it. I've always been careful to use cymbal sleeves to protect it but because of the keyhole it tears them up rather quickly. How well do the grombals hold up? And if I get those to use do I still need to use cymbal sleeves? Also do the grombals compromise the sustain of the cymbals at all? Any advice is appreciated.
