Rick,
Half of this rig is similar to what I'm using at the moment. My
Sennheisers have a similar polar pattern

nes_broadcast-eng-film_k6-series_003284?Open&row=3D2
but are a ridiculous price. Stick with the ME's, I just happened to
have the MKH's.
The one problem with getting stereo from a coincident pair of gun mics
is getting a good centre image. A 60 deg angle works with lower
frequencies and the human voice, but with higher pitched sounds like
warblers etc. there is a distinct fuzziness in the middle. A
coincident pair is also better if they are coincident as with the
capsules one above the other.
I've also been experimenting with a third mic in the middle panned to
the centre which gives a clean centre image but that is a ridiculour
rig. I'd recommend trying the mics close, and for birds, trying an
angle of 30 or even 20 deg. On the polar diagram 30 deg gives a clean
crossover at 6KHz.
The ultimate test is if you can reverse the phase of one mic and it's
worth making up a lead to do this. You can then hear where and
when the mics cancel out each other, the opposite of reinforcing the
centre image when they are in phase.
