Nigel, thanks for the reply.
I've been digging into this, and using a cardioid doesn't seem to be the best solution. Everyone seems to use the omni electrets.
Are you familiar with using mics on the soundboard?
I wonder if I put one at say the upper left corner, and one at the lower right corner, if I might get a good balance of sounds/tones. And then blend that with a bridge piezo mic maybe.
Oh, and as far as soundboard mics, i'm thinking specifically of putting them on top of the sound board.
