Thanks for your feedback.
I really like this paper - after seeing most of my prints on Photo Rag (which is still my favourite) it's refleshing to have a variable surface, particularly great for earthy subjects (sand, water, leaves etc). I'm considering printing my entire portfolio on this paper. I would have a custom profile made for this paper though if I decided to do so (which I did with Photo Rag with excellent results).
Yes, MK is probably right, given that Photo Rag Satin is still a cotton rag paper.
