vegeta, with whatever microphone(s) you choose, I just hope that you'll record in stereo.
People sometimes don't think of recording spoken word material in stereo, but often you can't get a good miking position in the hall, so the recording is swamped in room reverberation. Even (or perhaps especially) in conditions like that, stereo recording and a good pair of headphones for listening will increase the intelligibility of the recording enormously.
Please pardon me if I'm preaching to the already-converted, but I'm amazed at the number of people who think that stereo is just an esthetic enhancement for music, rather than a practical issue for all types of recording.
--best regards
