I think the very fact that Sennheiser are to look at the mic again with a
view to changing it speaks volumes, I believe they have made a mistake with
the specs Walt, you are dead right, I would rather the basics of the
excellent MKH-60 be used instead of the 416

When the animals come to us,
Asking for our help,
Will we know what they are saying?
When the plants speak to us
In their delicate, beautiful language,
Will we be able to answer them?
When the planet herself
Sings to us in our dreams,
Will we be able to wake ourselves, and act?

In the case of my MS MKH-60/30, no, that's not right. A mix up to 50:50
side to mid still gives a good field depending on the circumstances. I
more typically use 60:40 giving the mid a slight increase in emphasis,
but not very significant as far as self noise. Sometimes even a slightly
greater side contribution works. So, the self noise and sound quality of
the side should be as good as the mid.
I don't do math on it, I get out in the field and find out what works.
Then let the math try and catch up. To be fair, maybe they were talking
about studio use, where such a rule might work, though I doubt it.
A MKH-30 limits the sound quality I can get in my MS, and the MKH-418S
uses a side that's much worse than that. I see no reason to be so
limiting. Their side does not even come up to par with their mid or to a
MKH-416. So it's a poor match.
