Yabia Omer, I am a strong Ashkanazi following the Chasam Sofer but a big advocate of the Yabia Omer having all 12 volumes and Yechaveh Daas 7 volumes. He researches all views when paskening a halacha. I follow his views when it comes to tircha deztiburei, not to put any extra burden by the Shatz or individual on the tzibur.
