Been going through the same experimental phase with paper. I've tried a few of the less expensive options, and thus far I have to say that the stuff I got from Red River Paper has been the best of the lot. Both Leonore and I printed our postcards for the exchange on it, hers on 88lb. Polar Matte and mine on San Gabriel Baryta 2.0. The biggest difference between RR and some other budget papers is the blacks, which are deeper on the RR stuff than anything else I've tried.
