This is one reason why tracking on forward endfire is so futile, as well as a damn good reason the sphere doesn't listen 360 degrees.

Well .. what about NB ? You would need pretty strong signal to mask other frequencies too. It is true that DW clasification filtering does not work very well with 2 (or more) contacts at the same bearing. It will usualy interpret the lines as something totally unknown. But still you can mark, and with some practice, even classify manualy.
