Of course, you might consider doing you own tests to define the "speeds" of your own filters-either in sets, or individually. Steve Anchell's book gives good instructions for making such determinations without the use of a densitometer, and Ralph Lambrecht in his legendary and encylopedic Way Beyond Monochrome also presents a bit more technical approach to making such "filter speed" determinations. I also believe that Nicholas presents, on his web site ( Darkroom Automation ), detailed instructions for making " tone test strips" ( my words, not his )so that various tones can be easily obtained with each grade with each paper you use. There are methods to proceed should you desire, and have both the inclination and time.
OTOH, I believe that Maris and blightly make an excellent point, and their method is the way I am currently working as well. It is the "method" taught in the wonderful book by Carson Graves. It should be pointed out, of course, that when one changes grades of paper so that the blacks are "correct", that the exposure for the highlights also changes. However, you tell us that your filter set is speed matched for the highlights, and so such highlight exposure changes are not likely to be difficult to find. Note that if the highlights and the shadows are to your liking that the intermediate tones will "fall into place" ( as explained by Mr. Graves ).
