Very good summary to get people started, Teoh!
Re. waterproof ink: No one seems to know how De Atramentis Archive Ink is different from De Atramentis Document ink. But the Document series is just as pigmented and waterproof. And there's a modest range of Document colours. In my fountain pens I've had no problems with either D.A.'s Document, or Platinum Carbon.
