Developing with Rodinal and Fuji Acros II

I recently developed Catlabs 320 shot at ISO 320 in Rodinal 25:1 dilution with constatant CW and CCW rotation for 9 minutes @ 20 degrees C. The results were impressive. I would like to try Acros II in Rodinal now. Massive Dev. Chart recommends :

1. ISO 100 @ 50:1 for 8 min @ 20C

2. and ISO 400 @ 25:1 for 7.5 min. @ 20C.

Do any of you have any comments?

Since Across is a modern T grained (i.e. sharp toed) ISO 100 film, I would recommend a push to EI 400 only if you really want that kind of result. It basically depends on your personal preferences and it's a decision, which you will have to make. An EI400 exposure will give you weak shadow regions no matter how you develop.

1 - That seems reasonable.
2 - I agree with Rudeofus.

I've used Adox Rodinal with the original Acros with good results. Haven't tried Acros II yet, but I'd hope it's similar.
It's been my favorite for low-light shooting due to it's reciprocity characteristics.
This was at ISO 100 in Rodinal 1:50, shot on 120 film. Don't recall the dev time, but I would have used the Adox recommendation. The straight print still has plenty of shadow detail, but I've printed those down here to get the effect I wanted.
