Thanks everyone. Lots to consider, but I'm thinking D76 stock or Perceptol stock. For the latter, Ilford gives times of 14 minutes, and 9 minutes for EI 25, so I'm deciding if I should pull it a bit early to compensate for the bright flash. Sounds like I should err on the side of underdeveloping, in any case.
I'm also ordering more of this film...
Well before you order, make sure you like the results
However as a big fan of PanF+ I fully support buying more
