I'd go w/ tlw's suggestion.  When in doubt try a SDC centered and then move outwards.  Once you find a place you might want to switch to a ribbon, which might work if you are getting a squawky sound or want a more vintage sound. 
 
Stereo and double miking introduces the pitfalls inherent in those techniques for such a unique instrument.  It shouldn't be that hard, but most of us don't have experience so it is trial and error.
 
Good luck!  Let us know how it turns out and how you did it.

If it's any consolation, amplfying the things to compete with a loud electric band and drummer without PA or foldback howling away is even harder.....

And the reeds push out an awful lot of upper-mid frequencies which condensors can make sound brittle or harsh unless tamed by eq.
