Bainbridge and Crescent each have multiple "conservation" series boards.
Crescent has Crescent Rag which is actually a brand name for the cotton-based boards with the colored face sheet. That's probably the one Jerry's recommending. They also have the Museum Rag, which is a solid rag board. Now they have the Select Series of purified wood-pulp boards.
Bainbridge has the Alphamat series, another purified wood-pulp product, and the AlphaRag, which is a solid rag board.
All of these will cut differently. Personally, I think the AlphaRag cuts cleaner than the Crescent Museum Rag board. If you like the way Tru Vue cuts, you might also like the Alphamat, Crescent Select or even L-J's Artique line. All of these are purified wood-pulp alpha-cellulose boards.
Don't know about you, but I have a headache now.
