I'll be a nuisance again, :bigsmile: but the guy asked about archival quality, which has nothing to do with original PIE/PIF scans, but rather with long-term stability, isn't it?
For this purpose, if TY is chosen (there are cheaper alternatives out there, like MBIPG101 R04 under Imation or MCC004 under Verbatim), better go for the 16X (+R or -R) or the 8X +R. TYG02 is not really archival quality media, at least the official stability tests are not very good, and there are several reports of too fragile discs. Give credit to these reports or not, better play safe and buy discs with the least problems reported.
Once again, original PIE/PIF scans have nothing to do with stability, and not even with overall media quality in most instances. It's like judging cars from their MPH alone and disregarding the rest.
My personal advice with TY is still YUDEN000T02 (8X +R) if you can still find some, then YUDEN000T03, then TYG03.
