Neopan 400 is my standard 400 emulsion of choice. While I do not practice zone system or BTZS, I find it is a superb film. MY developer of choice would be Pyrocat HD. This film and dev combination is truly a great match. I rate it at box speed, but it can tolerate some over exposure for making sure you get all your shadows exposed. That said, during pyrocat HD development, I have yet to have highlights block up or flare. All my negs are developed for printing on a Dichroic head enlarger, and they also work well for graded paper printing.
This film has tremendous latitude, and with Pyrocat, you will not be disappointed. It's simple and consistent which is what matters most to me as thinking about all of the technical aspects will detract from the actual image making process. IMHO..
