My dad was sponsored by Sabian, Ludwig, Remo and Pro-Mark back in the day. His name is Tim Gehrt if you want to look him up, he did a lot of session stuff for example Glen Hughes and Steve Walsh's solo records. His big band he played in was called "Streets" and it was the band Steve Walsh created when he left Kansas. All that being said is that I really trust his opinion on gear and anything with drums. He told me a long time ago that the only thing he would ever use on his cymbals was a can of metal polish called "Never-Dull" made by a company called Eagle One I think? Anyways I use that stuff and it is truly incredible, you can put some elbow grease in and get some serious oxidation or anything out. The only thing to be careful is that when you are going over the print on the cymbals you can wipe off the print. Other than that they are awesome and I always recommend it. Also its super cheap you can get it at wal-mart.
