Zultan 15" Heritage Hi-Hat

I've had these for 1 day and I'm really impressed. The cymbals are heavily hand hammered and lathed, giving a lovely mellow, old-school sound with warmth and some complexity, but they still cut.
I've listened to a LOT of cymbal sound samples over the years (I'm a drum nerd!) and the Heritage hats sound to me like a mix of Agop 30th Anniversary and Zildjian Keropes. Both those cymbals are double the price of these hats which makes these a bargain!
My only slight issue is that the centre hole for the bottom hat is a tiny bit off centre, but it doesn't effect the sound or playability.
For anyone interested, the weight of my pair was top - 1040g, bottom - 1200g.
