I've used Neopan 1600 a few times, exposed around 800 and developed in Microphen. I used 1+1 for 5min. I think it's a good film for 640-800, but not 1600.

I've used TMax3200 exposed at 800 to 1000 and developed in TMax developer according to instructions for that speed (which gives not much contrast). That suited my choice of subject, but I think that it's too grainy for a subject which is small in the frame (e.g. stage photos with small faces etc)
