Avram in MD:
Whoa. Not just any rabbi is a good assistant or wise counsel for a beis din, and not just every beis din is good for any rabbi. There is a matter of experience in the subject, and the knowledge about how specific rabbonim and batei din work. The rabbi that “knows you well” might possess many great talents and skills, but that does not guarantee that he has what it takes to give the best guidance when involved in a beis din. I am personally talented in several areas, but I cannot perform surgery or play violin. You are certainly correct in drawing attention to the “knowing you well”, but there is a particular skill set and other variables that are equally relevant.
