Have you used Ilford XP2 (C41 processing) in the 120 format? It's all I shot when still using my Bronica 645 a few years ago. Super fine grain - amazing results. Although it's getting harder to get a lab to process that format anymore.
Have actually been thinking about that. I reckon after my exams are done I'll come see you (late November onwards) so we can have a chat and find out when suits you best Veilchen and I are going to make a little weekend trip of it probably
