He looked up smiled and said “Ah vort fun der chazon ish. Far zei haben gedavent sfard zei haben gedevenet ashkinaz. Un zei haben mishana givven שלא כדין!”
Bringing up a pet peeve of mine (so this may be a more irrational post)... So the Chazon Ish said yotzros and the right tunes etc, as if you look in minhagei ashkenaz they seemed to be pretty obsessive about that... Or HE could change it "kdin" (cough cough hoiche shmona esreh lechatchila cough cough)... but others aren't given that right...
Litvishe weren't iconoclasts when it came to tfilla? Just they changed the mesora of nusach based on how they understood the gemara, which the AR seems to have been busy with as well (nothing from after a certain period etc)...
As usual I don't know the sugya well (at all?)
