sloppy dice, drinks twice

I think in your case, the two mics would probably work better - but even so, it's more a matter of proper placement. More mics won't = a more balanced mix, but spacing out your mics evenly between the instruments will. Probably your best bet is to get a sample, listen and analyze it, then adjust the mics in between songs.
I once got a recording of an old band by placing a tape recorder in the middle of us. It was on a hardwood floor, even. The quality was not great, but you could hear everything fairly clearly.
