Have you ever tried the Warmtone variant of MGIV FB paper? The first time I started using normal MGIV FB, after having used AGFA MCC111 for quite some time, I was disappointed with the results, especially the blacks compared to the very deep ones of MCC111. Although I am now better able to manage the paper, and can get very acceptable results, I still feel the Ilford Warmtone MBIV FB is the superior paper in terms of total contrast and deep blacks. It get's very close to MCC111, even developed in plain Ilford Multigrade developer.
It's my prefered paper at the moment, even though limited availability here in the Netherlands of the Warmtone variants...
