I'm looking to push Acros - not by choice, but because I'm traveling and, although I ordered extra film, I was sent tri-x in 35mm rather than 120, and now I'm screwed because it's too late to order any more film. This is for a once-in-a-lifetime trip to Bhutan, which starts on Friday for me (I'm currently in Thailand). If Acros doesn't push well at 200 or 400, then I guess I'll stick to 35mm for low-light shots. However, if anyone has had success with pushing Acros I'd appreciate any info you can provide - speed, developer, look, any issues....

I usually use Rodinal or D-76, but I also have xtol, and could possibly get HC110, although I've never used it. Most other developers are not available to me in Japan, other than Fuji ones which I assume most people are not familiar with.
