Hi Mark,
Good to hear you have found some uses for your pair of KM86's.
I acquired a pair a couple of years ago, and though they don't come out that often they can work very well when they do so. In the right situation they can be good woodwind mics, orchestrally, but very useful as solo spots for a bit of gentle enhancement in chamber recordings, especially with odd selections of instruments in quirky layouts, and most useful, I find, as little spots in a choral / vocal situation where the fig8 pattern can be very handy.
