If you haven't seen it yet, Menachem Butler has uploaded R. Hershel Schachter's latest article in the YU Torah journal Beis Yitzchak. You can download the Hebrew article here (PDF). It is on R. Joseph B. Soloveitchik's attitudes towards halakhic rulings, in particular about whom one can trust to properly relay past rulings. And R. Schachter repeats the story about R. Soloveitchik's opposition to, but slight tolerance of, metzitzah be-feh.
