I believe I saw John, and Anne, use Colormount, when I attended their workshop in November, with no complaints or negative comments, about it.

I don't know of any studies that comprehensively look at the performance of the entire sandwich of mat boards and tissues, rather than of focus on just one aspect of a component. Anyone?
