I've mentioned to a few people the ink project I'm working on and also mentioned here about the dmax I'm able to achieve on Arches Watercolor (un-coated) paper. I'm starting to write it up now, and the first few pages of the PDF might be of interest to some people on this forum. The (very incomplete) PDF for the new inkset arrangement is posted here:

Let me know your thoughts and suggestions. This is a beta and project that is not complete or set in stone. I am, however, about ready to scale it to the 7800, where some new and different issues will present themselves.
Note that for the 1400 family, Eboni-6 can be set up in this basic arrangement rather easily, though the inks are slightly different.
FWIW
