For those still interested . . . .
I've been burning the abovementioned TYs at 4x and was very pleasantly surprised to obtain that most elusive of Benq scans, a 99!
Well, I think to myself, maybe these aren't so bad after all, if they burn like this at 4x.
Then . . . .
. . . as an afterthought I did a TRT and got what you see below.
I did a 16x scan and the truth emerged. :Z
I have to say, this pretty much fundamentally shakes my faith in the value of quality scanning (and in Taiyo Yuden quality), if you can't even trust a 99! :a
