I'd also like to add Rhodia to that list.
I think sxl2004 might have meant to type Tomoe River paper. Goulet Pens has a notebook that uses that paper which is popular because it brings out certain properties of certain inks. For example, the ink Emerald of Chivor has a red sheen that only shows up on certain types of paper.
Some things to look out for in papers is texture, drying times, and bleed through. A fountain pen friendly paper shouldn't have too much bleed through though it may come at the cost of longer drying times.
