I remember reading about
this guy some time ago, he'll take in trashed cymbals and do a total rehammering job. Not sent him anything myself (yet) but have read a lot of good things. I've got an old cracked 17"
Sabian HH crash which I'm thinking of sending, if I do I'll post a report.
Obviously it'll be a lot more pricey than just experimenting yourself, but it's worth mentioning.
