The issue with 400 is it needs Xtol or the two liquid developers from Ilford. I have dislikes with all. The previous version of 400 worked fine with D76. The current version is terrible unless you like hugh grain.

It is really nice film in Xtol or DD x, but I have had consistency problems with both. T Max 400 and my homemade D76 is my choice for 400 speed.
