I use white printable CD's and definitly NO lables, just to clearify it see this other image in my album :
It's not that I find the quality of these disk is extremly good, as it's just average. 1 or 2 out of the spindle give an error while burning, but that are average numbers that count for most 50 CD spindles I use.
What I like most on these discs is that the printable area goes on the the center hole of the CD. Most other discs stop half a centimeter earlier, leaving a more open gap in the center...
And because I have a backup on my computer of all CD's I don't really care if a disc fails.... I throw it away after the gig and reburn it.
