And with omnis, unless you get real close, there's the rest of the
street noise. Maybe a PZM mounted on a board that can be adjusted and
aimed at the talent. Even 18" x 18" (maybe covered in felt on the mic
side) might knock down some of the street noise.

That's the greatest advantage of omnis. You can get real close. The
inverse square law is the best noise rejection scheme available, plus you
get a very realistic sound. Directional microphones in a noisy environment
are great for spoken word, but the more directional the mic, the more
aberrations you hear--bad things for music recording. And I don't count
PZM's on any size board as a good directional microphone.
