The Nusach is Not the Main Thing:
Sefer M’Zekeinim Esbonen relates that when the Bais Avrohom of Slonim zy”a established his bais medrash in Yerushalaim, his elder chasidim asked which Nusach they should daven in the new bais medrash – the Nusach of Teveriah or the Nusach of Baranovitch (there were some differences between the two). The Rebbe answered, “You could even daven Nusach Ashkenaz. The main thing is to daven properly!”
