Hello,
I would suggest the two bath developer Emofin from Tetenal. For details look at
[url="http://www.tetenal.com/f_photo_consumer_service_download_de.htm"]http://www.tetenal.com/f_photo_consumer_se...download_de.htm[/url], there you'll find
the document "Komplette Sammlung Beta / Zeit-Kurven".
Unfortunately it's in german and tetenal doesn't have it in english, but the beta versus time graphs are selfexplanatory. If you develop the Neopan 400 with Emofin to a contrast of 0.5, Tetenal rates the Neopan as 800 ASA (the table in the Document says rel. Empfindlichkeit 30 which is DIN 30. Tetenal defines sensititivity as 0.1D above background.
Of note each graphs comes with two tables, the upper table is for rotary processing, the lower table is for drum processing with 10s aggitation every minute.
Regards
Heinrich
