Yes, I have checked out NY3. I just picked up Nashville a couple of years ago when I first bought Superior. I'm in the south and you can't throw a rock without hitting 100 country music fans, 5,000 Alan Jackson wannabees, etc. LOL! The Nashville kit fits pretty well in everything I have done country-wise. Myself, I'm not a huge country fan whatsoever.
I will probably end up getting NY3 when I have some extra cash laying around. I use NY1 and 2 and Latin Percussion mostly. I'm not hearing much difference between the kit pieces in most all of these kits. I mean nothing that couldn't be mimiced by adjusting the tuning or eq or envelope. Most tracks I work on are replaced by a real drummer anyway.
BTW, I am looking forward to messing about with AD. I've been playing around with it since upgrading to X3. The only Adpak I'm interested in there is the Black Velvet.
