The thing is that 2 years ago Ritek was decent to good media, but that was 2 years ago, it's gone downhill since. Just google Ritek degradation or deterioration.
Gotta say though, I'm not recommending CMC either. TY or Verbatim, or anything Made in Japan (such as Maxells own MIDs) would be my choice. Cheaper discs, perhaps Ricoh, though I don't have any personal experience with their newer discs.
But of course, use whatever works for you.
Just my opinion,
