Brad is spot on.
We are trying to create a cure to a problem that doesn't exist to a significant enough degree, for it to be a big concern.
How many people have had problems with a cd-r master not being accepted or had one get messed up on the plant's time, not because of something you did or didn't do in premastering, but was a result caused by the medium itself? Would that mistake, if there is one, be rectified by using another medium? Mistakes can be made with any medium, as long as humans are involved. ITR, nothing is really failsafe, but than again the percentages where mistakes were made, not discovered, and made it down to the first 1000 pressed cd's, is very rare, IME.
