I don't know about them, but I have a sample of the Diamine Oxblood and I love it. I used it in my Pilot Prera F nib pen, and it was wonderful. Not too dry, and not too wet. It was perfect. I tried out the Rhodia Webnotebook, and the Apica C.D. Premium Notebook this evening. I really like both. At this point, I don't know which I like the best. I like qualities from both. The C.D. Notebook paper was very smooth, and a joy to write on. I will know in time, after using them more, which I prefer. I will be trying out other notebooks in the future. I do like that 7mm line, it is perfect for note taking, for ME. It may be too narrow for others. I find it perfect. I like the orange Webnotebook very much too. I love the rounded edges, and the feel of the exterior. The marker is nice, but not necessary. I like both of these better than the Black N Red. I don't like spirals, even if it is a nice spiral. I do however like the perforated pages in the Black N Red. If I mess up a sheet, I can pull it out. In the other notebooks you are pretty much stuck with it. I prefer to write in the first two I mentioned though, so far. The C.D. Notebook lays completely flat, and I LOVE THAT. I hate having to smash down a notebook, so you aren't fighting that little hump in the middle. That bugs me. The Webnotebook has the elastic band, and I like that. I also like the emblem on the front of the cover. The Apica notebook cover looks very nice, and it looks like it is more historical, and less modern, in my opinion. I'm just mentioning this, in case someone is interested in either of these that I have tried.
