doswin: you must be relatively young. Oberlander havara is NOT the same as standard chasidisha havara. Vien should be nusach ashkenaz, and shtreimlach 30 years ago were flattter an uglier.
I was always wondering why the vieners are all wearing shtreimlach today. You think they’d be wearing them if shtreimlach looked today the way they looked 30 years ago?
And besides chasidim are very makpid on mesoirah and minhagim. They should be thinking ” Why am i not following my father’s mesoirah and davening ashkenaz,mustache only, oberlander havarah, etc.” ( And Vien in Williamsburg changed to sefard. What’s up with that?? )
