BTW, I just got shipping notice from MIS for order of Paul R's C6b base, so soon I'll get to try out toning to neutralize the carbon inksets! Of all things, the empty plastic bottles I also ordered are backordered hence the delay.
I mentioned earlier that I wanted to try Awagami paper, but I've given up for now. The paper (Kozo Thin Natural) has somewhat random behavior trying to hold high density ink with black patches' L values going up and down, despite being well below the ink limit.
