My 000-18 is nicely balanced and great for blues/rag stuff, but doesn't cut when playing bluegrass with banjos and fiddles around...that's what the dreadnoughts are for. So 'too boomy' is a matter of taste and style. As far as being hard to mic, I think it's rather too few people know how to mic properly for acoustics instruments anymore.
RichM: I agree that Beneteau's are great, but personally I like Oskar Graf's guitars ;-). BTW are you the same Rich McCarthy I know who plays upright bass among other things????
