I develop Acros in Rodinal, usually 1:50, rather than D-76. The high-end results are about the same with either.

Rodinal is a compensating developer, which gives greater highlight definition and control.
It wants very little agitation. It doesn't work right with rotary processing, nor for high-ASA films (400 and above).

Rodinal is ideal for small-volume users since the concentrate keeps indefinitely, even in partially-used bottles.
People have reported using concentrate over 50 years old that still performed like new product.
The working solution has a short life, a few hours. It should be mixed right before use (allowing the temperature to stabilize).

BTW, due to some trademark bull, Rodinal is no longer available under that name.
It's now known as R09 and one or two other names.
