A few weeks back I posted something about using a substantial proportion of Best Dark Munich in a 1.050ish dry stout as being the best dry(ish) stout I ever tasted. You could certainly go 100% Munich, but as mort says, a little pils might help dry the beer our some.
Still have that beer on tap, on nitro, and it is wonderful! Have 5 gallons in a pin I am saving to put on beer engine for St. Patties Day.
