If tonality, fine grain, and sharpness are what you are after, I stand by my original recommendations. T-Max 100, Delta 100, or Acros. Maybe PanF+. There are finer grained films out there, but a lot slower and sometimes contrastier. They are certainly worth using, but I'd try the films above first and if they aren't going to cut it, look into some of the more specialty films and/or 4x5.
