[Avodah] changing nusach

[Moshe Y. Gluck]

R' YL:
>> I believe the Reb Moshe has a teshuva in which he says that one can
>> switch  from Nusach Sefard ... to Ashkenaz, because virtually
>> everyone in  Europe davened Ashkenaz originally until the advent of
>> Chassidus.  I am  not sure, but I doubt that he would approve of
>> someone who davens Ashkenaz  switching to Sefard.


R' Ben Simpleton:
I was told Rabbi Abadi permits anyone to pray Nusach Ashkenaz in a
Ashkenazi shul. Nusach Edot Mizrach in a Sephardi shul, Temani in
a Temani, etc. Never heard if he says it is permissible to enter a
hasidish shul.
---------------------

These are two different issues; R' YL is talking about switching Nuschaos
completely, IOW, changing from the Nusach his parent used to a different
one. R' Ben Simpleton seems to be talking about a visitor to a Shul which
davens a different Nusach than he's used to, that he should use the local
Nusach. R' MF says the same thing, except for the parts of Tefillah which
are said silently (presumably just Shemoneh Esrei), that one should use the
Nusach of the local Shul. 

I was once in the Vishnitz Beis Medrash in Monsey, and a non-Chassid was
being Baal Kriah in a Shacharis Minyan. He tried very hard, rather
unsuccessfully, to Lein with a Chassidish Havarah. I thought he was being
foolish, but then he told me that he was doing it because of R' Moshe's
Psak, and I realized that he was probably correct...
