I make black and white prints using a Canon PRO-100 too, in my case on Hahnemuhle FineArt Baryta Satin. Have you tried that paper? If so, how would you say it compares to Big Bend Baryta 310, especially in terms of surface gloss? Thanks in advance.
In the past I've used that paper and just happen to still have a box with a few sheets in it. Viewing a sheet of the Hahnemuhle FineArt Baryta Satin next to a sheet of RR Big Bend Baryta 310 in an indirect daylight lit room, I offer the following observations:
1. Big Bend Baryta is quite a bit whiter vs the Hahnemuhle paper; the latter taking on that "yellow" warm base color.
2. The surface gloss of BBB is noticeably glossier vs the Hahnemuhle, but nowhere near the gloss look of typical RC glossy papers.
3. In the hand, the weight of both papers feels the same, though I believe the Hahnemuhle paper is ever so slightly thinner.
Since I tone my B&W prints to a warm sepia, the BBB paper works fine for me and is cheaper than the Hahnemuhle paper. That said, if I had an image requiring a very warm treatment, I wouldn't hesitate to print on the FineArt Baryta Satin paper.
Hope this answers your question.
