A different nusach

Hi,

If one davens with a minyan in which the standard nusach is different from his own, then for all parts of the davening which require a minyan, whether recited aloud or recited quietly, one should use the nusach of the minyan.

(Rav Moshe Feinstein, Igrot Moshe Orach Chaim 2:23)

Note: In Orach Chaim 2:104 Rav Moshe stated that one should use the nusach of the minyan for everything other than the silent amidah.
