I have read somewhere that Delta3200 was good, say, shot at 1600 and developed as per box instructions for 3200, or shot at 3200 and processed as per 6400. Developer Ilford DDX and gentle agitation every minute.
I personally tried the first example and was not disappointed by it, a bit of grain but didn't mind (the film was expired for about 4 years).
Hopefully some more experienced users can give more details.
attached a quick sample neg scan (bit soft, i know)
