Hello drummer friends, this may be a nonsense question but I've seen a pair of Paiste 2002 "Rock" hi hats black label (possibly from around 1979), good condition at decent price. I currently have PST 7, I've had them a long time and wouldn't mind swapping them out. Do you think this would be a decent upgrade? Tempted to go for them, just wondered what people think. Unfortunately can't afford new 2002s.
