Reply To: Changing to a different nusach

I recommend you read the Noam Elimelch at the end of his sefer in one of the letters,it is a very powerful message on nusach sefard.Rav Moshe holds that to switch to ashkanaz is never a problem,but he does mention that those who daven sefard must be allowed to and not assur.Rav Henkin discusses this un Gevuros Eliyahu,will look it up.
