He also mentioned that the current AKG capsules, at least the ones that he has, are identical to the original capsules in my mics and that changing them would not make them sound like new 414s (i.e XLS) which I do not like nearly as much for my application. I'm a little skeptical about this, but I really don't know.
They might have been a little noisier than the much newer XLII pair that I compared them to, but I far preferred the character of the sound of the older mics.
