You also have to be careful with black substrate CDs (if that's what you got) because some drives don't read them (crappy Liteons and Liteon/Optiarcs, I'm looking at you). Also your discs sound like they're plain silver which means the reflective layer is exposed, and thus the disc will be easier to damage than a printable disc or other disc with some class of top coating.
It depends on the use you have for the discs - if you're giving away promotional data CDs, your pack of Prodiscs will be great - they'll do the business and the black bottom will be an attention grabber.
But if it's something your getting paid for, or something your customers will want to keep for a long time, the Taiyo Yudens are the only answer.
If it has to work, it has to be Taiyo Yuden.
