Reading Tim Rudman's Master Lith XYZ, MG WT does lith in a slightly unorhtodox way if and only if the dev is about 40+ degs C I recall. Tim says it has a particular look and is not for everything, but some of the results he showed were wonderful. Try it hot.

Look out for Kentmere papers as many lith as well as Oriental seagul, Fotospeed Legacy I hear does, Forte PWT/Fortezo etc.
