Aseih L'cha Rav

We are admonished to make for ourselves a "Rav".
Q: What if one is already a Rav?


Recently I was told that a prominent MO Rabbi had three "mentors"
The Lubavicher Rebbe
R Moshe Feinstein
R Yosef Dov Soloveichik [the Rov]
Zichronam Livrachah

Then it occurred to me. If you're already a Rav, then you need a Beit Din. The Beit Yosef himself devised one - namely
The Rif
The Rambam
The Rosh
Z"L

Not bad and hard to beat

Reputedly the Kitzur SA had a B"D of
Derech Hayyim [N'tivot]
SA Harav
Hayyei Adam

A Colleague similarly suggested a B"D of
Mishnah B'rurah
Aruch Hashulchan
Kaf HaHayyim.

The three major early 20th century codes.

If you had to choose just 3, which ones would you choose? More contemporary or further back in time?


Shanah Tovah,
Best Wishes for 5773!
