I'm with Chuck. I'll also suggest ORTF (110 degrees, 17cm) which I tend to prefer over DIN if the room sounds good and you can put the mics where you'd like them, which tends to be closer than the offical taper's section, even on-stage for some things. It can work well outside from farther back too. DIN can be a better choice in less ideal situations (farther back, less than ideal rooms, etc) partly because the mics are facing more towards the source and that configuration is slightly less sensitive to off-axis sound arriving from behind.
The relationship between microphone pair spacing and angle is inversely related. If you take a look at the two configurations we've suggested, DIN is spaced a bit more with less angle between mics and ORTF is spaced less with more angle. Both are simply two fixed configurations along a continuum which runs from X/Y with the mics facing 180 degrees apart to A-B spaced a few feet apart with both mics facing directly forward (you can go wider than that too, which you'd usually only want to do with omnidirectional mics). If you are interested in how that all works, check out the threads here which discuss the Stereo Zoom, a technique for determining any spacing and angle.
