The MKH-8070 is an update of the MKH-816 and appears to have a better
polar pattern. I have two 816's which I use in stereo and these are
available at a fraction of the price on eBay. I would suggest trying
one of these first before shelling out on the (possibly marginally)
better 8070. What either mic will give you is a large solid angle of
reduced sensitivity which will give a cleaner recording than any other
type of hand held mic. The 816 was the mic I'd get my boomswinger to
pull out of the car if traffic got difficult.

The Sennheiser MKH series has a reputation for robustness and I've
used them in rain and got them wet and they didn't complain. The low
voltage RF bias is part of the secret.

However, no long gun mic will give you good separation from bass noise
which in any case often reverberates and diffracts all around you. A
tailored high pass filter is about the only answer.

A friend of mine is a Schoeps dealer and I've had a play with a
Super-CMIT. It has remarkable side and rear rejection with the option
of a small back lobe if you really want to avoid all digital artefacts
but it pulls 170 ma and gets warm. Definitely an indoor mic but the
way it gets rid of the room acoustic is remarkable. The CMIT
is an excellent mic with a clean sound but is simply not long enough
to give a good low end rejection.
