2 suggestions, one, can you go there? Run a test...
Personally, if you're shooting Medium Format, Delta3200 won't disappoint even at 3200.
If you're near a lt of direct light from the window, 3200 shot at 3200 developed at 3200 should be great, if there are a lot of shadows, I would shoot at 2000 and then develop at 3200.
All in DD-X
