I understand the "real" purpose of Lenox is for intaglio printing where high absorbency and high loft are desired for lots of ink density and visible embossing from the plate. It seems to resist changes in humidity, that is, it takes longer to dry it or to humidify it, but when you find the right humidity level it is a wonderfully easy to handle, forgiving paper to work with in Pt/Pd. You may want to use a first clearing bath of citric acid (2-3%) and then EDTA/sulfite: without the acid clearing you *may* see a very slight overall yellowing of the entire sheet but this seems to fix it right up.
