The Innova FibaPrint Ultra Smooth Gloss 285 GSM has become my favorite paper for B&W (which is mostly what I do). I did quite a bit of testing and sampling of all the current PK papers and the Ultra Smooth Gloss had just the right combination of characteristics for me. It does not seem to suffer as much from gloss differential like some of the other PK papers (e.g. Gold Fiber Silk), the surface texture is pleasing (for me this means it's not too sparkly, too obvious, or too high-gloss), the base color is a bright white but not blue (although it does have OBAs), and has a nice hand feel. I use "Premium Glossy 250" as the media setting for this paper which seems to match it quite well in terms of ink load and paper handling in my 7900. Most of the time I'm printing with "Neutral" and either "Normal" or "Dark" settings in ABW and I'm getting some of the best B&W work I've ever done.
