Yes, let us know what you picked. I'm sure we can all come to our own conclusions.

I've done the same kind of test and among enlarging papers (I prefer graded papers), I like the tonality of Cachet (Maco) Expo best for its ability to hold shadow detail, with Oriental Seagull also up there when I want a colder tone. I've also recently discovered Luminos Charcoal R, which is made by Kentmere, and has a place for certain types of images--a warmtone emulsion on a base that feels like watercolor paper.

For contact printing, I use Azo.
