[sorry if this topic is redundant, I'm not a daily visitor]
For the past few years I've been printing with acrylic inks on either 80# cover weight Cougar Opaque. I like it better than French for print qualities and economy, but the paper tends to warp/buckle a little over time in the climate here in DC. Humidity kicks this paper's ass, as does tension of the ink on the surface. I tried 100# too but wasn't much better, and is a pain to trim down (I don't have a guillotine).
What do you like printing on? Would prefer to order by the full carton from a larger distributor such as Xpedx.
