Hi Mo,
There is another option. You could use the Canson Baryta and Platine. These paper are excellent. The profiles are almost identical(I mean really close). It's also rumored that Canson is making the Epson line (both made in France). The rumor also says the coating is a smidge different (that's a technical term) and I suspect that accounts for the slight difference in gamut. Also, Canson is 25-33% cheaper in the U.S. Again, just a thought.
