Hi there, just to close the loop on this discussion, I acquired the Canon paper and so far so good. I've enjoyed the prints I've made with them, and it's now my go to "cheap" paper when I want to play or experiment a bit. In terms of feel, it's very close to the Epson but I think more discerning folks could probably notice they aren't the same paper. I'll also note that using the Epson profile worked "ok", but was noticeably off in some ways in the one random test I tried. I created my own profile and was happier with those results. Not a surprising conclusion, I assume.
Cheers.
