What do you consider "larger prints"?
Well that really depends on how they are to be mounted. But I would consider the Aurora too thin for floating above 8" x 10", for for edge under matte, perhaps 12" x 18". Lighter paper can go larger, but not with a tendency to recurl.
Also, what do you think about Red River Aurora for strictly B+W, would the gamut still be an issue?
I tested it against what I was using at the time, which was Hahnemühle Photo Rag 308. I have been using Canson Rag Photographique 310 for some time now - the Hahnemühle paper has some curling issues of its own. I do not consider papers separately for color vs black and while.
The Canson paper lies flat, is whiter, comes in 310, 210, and 220 C2S, and has better color separation in the dark greens.
But paper selection is very much a personal thing. The only way to know is to buy sample packs and try them yourself.
