I personally love the look of Tri-X or HP-5+ (ISO 400) pushed to EI 1000-1600, especially with Acufine developer. If I need very fast film this is what I usually do since the 3200-speed films are more expensive (and anyway my favorite, Fuji Neopan 1600, is no longer available).

Sometimes I rate 400-speed films at 200 and develop normally (no pull), especially when using the view camera (it's not something I arrived at scientifically, it's just insurance against miscalculating the bellows factor). But if I want a slower speed film, I just get something off the shelf like FP-4+ (ISO 125).
