Fitzwilliam Choir - arrangements

I'm in the middle of arranging the first event to record for my portfolio. Apparently, there is a choir singing in the Fitzwilliam College, my place of work, and most propably they will allow me to record their performance in College Chapel - looks like a good opportunity to use some nice stereo array. I am thinking of using a Marantz portable digital recorder and a pair of C414s.

Before the event, I'll have to check the notes on stereo arrays from previous year. For now, I am still waiting for confirmations.
