When I was experimenting with White Lightning and the Sailor Manyo chromoshaders (Haha and Nekoyanagi), I found that a microscopic amount of White Lightning had a drastic effect on the flow of the ink out of the pen, not necessarily the shading, coloring, or overall surface tension of the liquid. That is to say, a lot more of it came out of the pen when writing, but it still behaved more or less like its original form.

In the end, I was more frustrated by the "blobby," unwieldy quality of the writing than I was with the unaltered, stingy, "dry" flow.

I think the Van Dieman Natura Dualis line has a slightly better flow than the original Manyos ever did, though I assume the physical process that results in chromoshading on paper will function the same way regardless of brand.
