well.. whoever might be interested.
i have found ortho 25 (120) to work very well with minimal agitation in pyrocat-hd.
exposed at iso 12, and developed for almost 16 minutes with 40" gentle agitation at the beginning, 10" at 3, 6, 9, 12 minutes.
shadows are fine, highlights not blown out. in higher contrast scene might need even a bit less development (and therefore slightly longer exposure).
