Raavad
- במספר חוטי תכלת אם עשה כשיטה אחרת והכרעה במספר החוטין – הרב יצחק ברנד
- חוט תכלת – בראנד, הרב יצחק
- בדין מספר חוטי תכלת וסדר הכריכות והקשירה – בראנד, הרב יצחק
  Short version:
  - The Sifri pretty much explicitly states Raavad’s shittah;
  - The Beis Yosef/Kesef Mishnah had an incorrect Girsah of the Raavad and assumed that he had the same opinion as Tosafos;
  - In absence of a solid mesorah (which obviously no one has in regards to Techeiles), you should use logic to decide the Halacha (instead of Paskening by ethnicity), which is what the GR”A did when he Paskened like the Raavad.
