For head shots with extensive B/D, do the perfect print and then make a copy neg with say, Techpan or Ektapan. With the right processing TP will render an extremely long scale neg (I use Divided D76 and rate it at 80). This way you will do production runs and by using Ethol LPD (a very long lasting print developer), you can pull this off easily with hardly any degradation!!
