I've been using Delta 100 for about 8-9 years now, I get box speed and superb shadow detaol and separation, just as good as I got with APX100 and Tmax100 (at half the speed of Delta 100 & APX100) in the past.
For more speed I use Delta 400 in 120 and HP5 in sheet film. I have push processed 5x4 HP5 to 3200 in Pyrocat HD out of necessity rather than choice and had far better results than I expected, I was shooting a moving object at 1/50 and f5.5, so pushing was the only option, I might go a stop over HP5's box speed in future depending on the subject matter and whether I needed shadow detail.
