Actaully I withdraw (partially) what I said about the TYG02s. (I'm in Ireland BTW)
I just rechecked 6 out 10 of a pack of "Datasafe Pro" branded TYG02 - and 2 of them showed signs of poor quality. That said, I know these are the Valueline type and I don't know whether my YUDEN000 T02s are value or premium, so the comparison may not be totally fair.
But between that and a 23 disc set of a hard to find TV show I got from a Canadian company (I have written of these from time to time) that were TYG02 BUT with very gooey paper labels. :Z Although I was able to make most of them (all but one) fully readable by scratching off the labels and an obscene amount of glue, in most cases I could not restore PI/PO readings to levels expected from a high quality media.
At the time I wrote that down to the ... unusual ... treatment I had to give the discs, but between that and this, I am no longer as enthusiastic about TYG02 as I would have been about 18 months ago.
Having said all that when TYG02s work, they work great. If you get confirmed Premium line TYG02 - and you don't abuse them - they should be as good as the best of anything Taiyo Yuden has ever made. I just have not found them to be as consistently good as my 100 pack of YUDEN000 T02s (TY 8x DVD+R) and my (better) MCC 004 and MCC 02RG20s.
What I like about Taiyo Yuden is that you know what you're getting when you buy TY. With Verbatim, they make stuff all over Asia, sell rebadged discs (no AZO CDs in the U.S. some of their DVDs are not even AZO) and quality varies from country to country, factory to factory, disc type to disc type etc. And I've had a few coasters/dreadful burns with Taiwanese verbs.
With Taiyo Yuden, when you find something good (like their CDs, 8x DVD+R, DVD-R DL, anything "That's" branded, you know exactly what you're going to get, high quality burns disc after disc after disc.
