I am glad there are others agonizing about this as much as me!
stokedchicken - based on advice I got from a professor that used to be on a Boren selection committee, the exact combination of components you have in your proposal is not the most important thing (other than needing to have significant language study of course). She said it's more about whether what you are proposing makes sense as a whole package, particularly in the context of your educational and career plans. Also what you are planning needs to be feasible given the amount of time you propose and you should explain how this is true. I am really hoping her advice was enough to help me get a fellowship! We will know soon enough!!
Good luck to everyone!! I am anxious to hear all of the results!
