Hi Mark,
I print for some very critical artists, and highly endorse the other recommendations here for the heavier weight Canson papers. I use almost exclusively their Velin Museum Rag (315 gsm) with a relatively smooth ('velvet') surface, or Aquarelle Rag (310gsm) where a more textured finish is appropriate. Also occasionally BFK Rives and Baryta Photographique for specific purposes. All museum-grade, archival, OBA-free etc (the Baryta does have some OBAs, I believe), and exude 'quality' in the hand.
I formerly used Hahnemuhle papers but found the Canson alternatives had a larger gamut, at least with my iPF8300, particularly evident in the reds. I also had two faulty rolls of Hahnemuhle Bamboo in succession (the original and a replacement from a different batch), so I have serious reservations overall about Hahnemuhle's quality control. Pity, as it's a nice paper otherwise.
The only caveat I have is that the papers can be susceptible to scuffing if handled improperly, visible as a slight 'polish' when viewed against very oblique lighting, but I suspect that's common to all similar fine art papers and is not specific to Canson's offerings. Other than that, no problems with normal handling.
Cheers,
Malcolm
