hello. im looking for the best choise for outdoor field recording and im a little lost. i need a stereo mic or arrange whith very low noise, high sensitivity and a response as flat as possible. Weather conditions could be little bad, and the locations could demand very long walks. i was thinking in the RSM 191 since there are appropiate wind attenuator accessories available for it, and should be more light weighted and easy to carry than a pair of U's for example, but i'm not sure. any ideas or advise?
