Since you're using TMY, which expands better than any other contemporary film that I've tried, it's a piece of cake. Place the shadows on Zone IV and then you'll only need to give the film +2 development to yield a negative which will print well on grade 3 paper. (at least that's what I do for Azo). Drop it a half stop on the exposure and give it N+2-1/2 development and it will print well on grade 2. Since you haven't done formal testing of your materials, you may wish to wait until you do if the pictures are important to you.
