Rob,
Thanks for the information.
Based on the charts and the $ I want to spend at this point, the mics of
choice are probably: 1 Sennheiser K6/ME66, 2. Rode NTG-2 or the 3. Audio
Technica AT897. =A0I am leaning to the Rode NTG-2 since it is more in
my price range. =A0But I am still considering what is right to do.
=A0I have listened to recordings of all 3 and the Sennheiser appears
slightly better with the Rode a close 2nd.
Again... thanks... I will share my final purchase decision later.
