I think that the word "rare" is inappropriate (although everything is relative) for the TRD 2-disc: probably it's not easy to find now, after 10 years, in stores, but if you seek online you find as you like.

Regarding the "swirls", I own all the versions (WG, USA, Japan) you mentioned and, even if it's pleasant to listen few more seconds, I can tell you that the overall difference is minimal
