(Btw, in my first comment I seem to have repeated some of your suggestion; I overlooked your first post)

In my view, New cyanotypes have two disadvantages: 1) the process is very sensitive to the paper base, and generally more difficult to coat, 2) - I think, though I have only made one or two very preliminary tests - they don't tone as well as normal cyanotypes.
Mike Ware gives very good instructions on his website, though I use hydrochloric acid instead of nitric for the first bath, because it is easier for me to get (he used to recommend this also, but changed it).
