[COLOR="Olive"]Well...the interesting thing about Azco Zilcos is...they ARE B20 alloy. They just weren't worked the way the regular Zildjian's were (i.e. very little hammering and the lathing was different/shallower).
As noted, once in a while you can get lucky ~ and end up with a nice sounding cymbal for some applications.
I bought a pair of 20"s back-to-back on eFlay a year ago with the intention of letting Matt Bettis have a go at 'em and do some rehammering/lathing. At the time I figured for $50/ea...I had myself a nice pair of B20 blanks, basically.....
They ended up sounding like such nice, dark, Jazzy sorta rides that I never sent 'em out.[/COLOR]
