@ zahavasdad: For your info, if you walked into the kashrus division of the OU and saw the rabonim there, you would think you were almost in a ‘heimsha’ holier than thou hashgocha. Let’s just say the yeshivas such as Ner Yisroel, Torah Vodaas, Chaim Berlin, Long Beach, Scranton, etc., are more represented there than YU etc.
That being said even the minute amount of “MO” rabbonim there, know more about kashrus and its practicalities than just about any “heimish” hashgocha!
