Old Man: you mean they’re universally said in Israel by all following minhag haGra? Or by roughly all Ashkenazim?
Avi: Hallel in shul seems to be one of the most widely observed of the minhagim mentioned here so far. I know us Yekkes don’t do it because it goes against the Rema, but is the Gra really the main Ashkenazi proponent of it? I thought it was much more mainstream than minhag haGra.
