I’ve printed on a wide variety of papers. I also have a C&P Pilot, and almost always print with dampened paper. I find that French Paper Co. Muscletone paper prints much more crisply than Lettra, and I use those as my stock paper (many wedding clients go with the Lettra because of the softness, but almost all my greeting cards are on the Muscletone). Mohawk’s new Letterpress paper (I think it’s a version of Strathmore?) also prints pretty crisply, but the surface has more tooth than French Paper Co. Muscletone.
