Allow me to geek out for a bit.  Ilford XP2 is an all around champ in terms of a Black and White film.  It is a color print film that renders only in Black and White.  So its native developer is C-41 BUT it can also be developed in traditional BW chemicals.  Not only that it has a wide lattitude and you can shoot it at ISO from 50 - 800 without major problems.
