Here's a fun thing to play around with for those of you running two (or more) pairs of microphones and/or mixing multiple sources-
Do an initial mix the way you typically would, then set that aside for later comparison. In listening to the two sources when making that mix, determine which has better clear, direct sound versus which conveys the ambient/diffuse material in a better way. Make a second mix which includes narrowing the width of the more clear/direct source and widening the ambient/diffuse source. Play around with the width of both in combination to see if you can improve the mix this way, both in terms of imaging clarity and "you are there" feel.
This can sometimes work really well by emphasizing the better qualities of each source, even to the extent that such a manipulation would be too much when either pair is listened to in isolation, yet when combined the two balance each other and blend better with less conflict.. or it might just produce a smeared mess. Tread carefully and use your ears to find the most appropriate blend of the two. Generally I'd suggest narrowing the width (increasing the sum) of your closer-spaced/more-narrowly-angled/more-directional source, and increasing the width (increasing the difference) of the wider-spaced/wider-angled/less-directional source.
An opposite approach to that is to listen specifically to the Left/Right stereo imaging locations of each source in isolation, adjusting the width of one so as to match the perceptual sense of the direction to each sound source in the other as closely as possible. This is more about matching clear and precise specific imaging locations between sources without smearing those apparent locations. However, in doing this we increase the degree of overlap between the two sources such that other conflicts may arise- congested imaging, timbral issues, less overall sense of envelopment, etc.
Personally, I find the prior approach more useful most of the time, which in a way is the application of Mid/Side to mixing in a general sense. But do whatever sounds right, take a break, then compare against your initial straight-up mix to see if what you came up with is actually an improvement or not.
