bubka – presumably you’ve heard of Harav Arvrohom Gurvitz shlit’a, Rosh Yeshivas Beis Yosef D’Gateshead (otherwise known as Gateshead Yeshiva) who once told a friend of mine “he’s not J. B., he’s R’ Yoshe Ber MiBoston”. I take it he’s charedi enough for you…
Personally, my wife and I learn shmiras shabbos k’hilchoso.
