For some examples of Neopan400 in PMK have a look at:

I'm using Neopan400 (120 size) in Pyrocat-HD and it's sharp! I use the metol version of Pyrocat-HD since I had some trouble with my first normal batch (probably my fault), and I use a film speed of about 320 and develop in dilute (3mL+3mL+500mL) with minimal agitation for about 18minutes at 20degC. (My agitation for what it's worth is constant for 2min, then a couple of inversions each 3min. Also, if you have a 250mL tank that would cover a 35mm film I don't know if 250mL is enough for a full 36 exposure film if you use dilute Pyrocat-HD)
My metering style is to give more exposure than a "point and shoot" use of an auto meter would give, because I think that this film's character makes it harder to salvage underexposed negs. If I was thinking of a setting for a "set and forget" auto meter I would set 200 or less.
This film works well in diluted developers, and also in Xtol 1+1 (and I have read raves about 1+3, but haven't tried it)
