If they had PanF+ in 4x5 I doubt I would even buy another film for daylight work.
If they could make a film with the characteristics of PanF+ and the reciprocity failure rates of Acros 100 I would never buy any other B&W film but Ilford.
But I digress. Point is I'm not the only one, and I doubt that delta rated at EI 50 dev in Rodinal pushed 2 stops would give anything like PanF+ because its only a 1 stop push in reality, which doesn't push the highlights enough, and I think the ability to not burn out the highlights in a push is another PanF+ behavior I like, at least on my system.
