Chamber music is a great idea!

I wonder whether someone else could offer input on flute. There seems to be a greater supply of flute players in the orchestra context, but as with any instrument, a good player is always valuable. But it isn't an instrument with which we have direct experience. Also, it probably isn't good to choose an instrument solely for its scarcity; a young player can end up in a cohort with lots of oboes and few cellos, for instance!
