Thanks for posing the question, though I think you already know the answer, Ink Goddess that you are.
When I first started looking at the posts on FPN I'd see people talking about "dry ink" and "wet ink", as well as pens, and I really didn't know what they were talking about. I only have limited experience with inks and a few pens, but compared to the other inks I have, the DeAtramentis Pigeon Blue is a dry ink. All my other inks in that Lamy 2000 have flowed very easily, but with the Pigeon Blue it seems like I have to slow down my writing for it to keep up, and my fast strokes are thinner than with other inks to some extent.
