Mamashtaleh, why the change?
There are 5 shules on my yishuv. All of them daven either Sfard, Eidot Mizrach, or Ari. The two shules where I daven are nushach Sfard. I decided when we came that I wanted to be a part of the minyan, and daven along with everyone else. I spoke to the Rav at length, and he agreed I should switch. (BTW, he himself davens Ashkenaz when not davening for the amud.)
There is one shule that has one minyan a week that’s Ashkenaz – an early morning Shabbat minyan.
