I use Photo Rag Ultra Smooth regularly, especially for graphic or bright images where colour vibrancy is paramount. I like the totally unobtrusive surface, easy profiling (I have my own custom profile and the manufacturers, both nearly identical and very good) and sparkle it gives to images. The closest paper I have seen to it is the Innova Smooth Cotton Bright White, but the Hahnemuhle seems slightly smoother and whiter. I would recommend it for landscapes, but bear in mind it does contain OBAs, so may not have the highest longevity - the Aardenburg tests will be interesting. For this reason, and because I like it, I tend to use the Innova Smooth Cotton Natural White (IFA 11) more often. Check it out, it's a beautiful paper.
