Also want to chime in that I think ORTF (110 degrees mic angles, 17 cm apart at the capsules), unless up close, isn't optimal further back. For that reason, I most often used 60 degrees, 30 cm apart. I think that setup picks up more direct sound w/ the Neumann's, and less reverberation from say, the walls on the sides. In fact, I applied a simple forumla, (180 - MicAngle)/4=# of cm apart for the mics, thus 180-60=120/4=30 cm apart. 180-40 (ever more direct) = 140/4=35 cm apart. Even made a moke inspired mic bar for this purpose with those settings marked. Worked for me anyway...
If you look at the Stereophone Zoom, those numbers/combinations all fall into the sweet area for cardioid mics (based on where ORTF lies).
