“Anyway, can anyone list a Rav that doesnt suggest this?”
Mine. He deals with individuals of the kehilla, as individuals of the kehilla. He doesnt issue cookie cutter guidelines or advice to anyone. To one he might suggest the 4 inch rule, to another he might suggest 6, while yet another he may make no suggestion at all. He works with everyone on their own level.
I guess the “how to halacha books” are for those who do not have a Rav. Baruch Hashem, my family has one.
