I've owned these for many years. Medium to medium/thin weight overall - definitely not heavy.
One has the 70s/early 80s "hollow" Zildjian logo on the inside, and I’d say this one is a slightly heavier “medium” than the other, so I would use it as the bottom whenever I played them. And the other cymbal has a faint ink "Top Hi Hat" stamp that you can only see in just the right light. Great pair.
