This was briefly mentioned in Mike's thread, and I've heard it mentioned before by some... so could someone explain?

It's been said that with some circuits, it's best NOT to use ceramic disc capacitors in places where orange drops would be normally be used. For instance, .01's, .001's, .047's. I have, on occassion, replaced old paper/wax .01's with a ceramic disc. Usually, I use ceramics with voltage ratings much higher than the set needs. For intance, if I need a .01/400v cap, i'll use a 1kv ceramic just for added peace of mind, and because I have a shit load of them at times. I would think that today's ceramic discs would be far superior than the paper/wax caps from years ago. But, many say that using orange drops or mylars are better.

Is there a specific reason to steer clear of ceramic discs in some applications? Are they too unreliable?
