I totally agree that Agfa MCC is a superb paper, with fantastic shadows. I've been using it for more than 3 years now. Every once in a while I try something else but always return to Agfa. It's also very good in Selenium, i.e. you can get a nice split in tones. As a matter of fact, I lugged several packets of MCC111 from the UK to a photographer friend in Turkey, because the paper is not available there. It's *that* sought after by some who appreciate it's qualities.
As you know, Agfa has a very light warm tone. If you ever feel the need for a colder tone for a particular negative, you may want to try Forte Polygrade. It has a similar tonal richness.
