Well - what I perceive could be attributed to psychology - but if I had to guess, I would say it is brighter and a bit more sustain than before, but not a whole lot more sustain. It is limited by the metal composition that it is. It surely sounds better, but it IS an old MIJ cymbal - not their strength.
I have not played it in context though. I am going to jam with it tomorrow with my '68 Slingerland, but then again, I have NEVER played this cymbal on any kit. I just acquired it this past spring.
Like I said, I will be shooting a video with the exact same camera as the MIJ Cymbals video and then I will be able to tell - or shall I say WE will be able to tell - I hope.
