..”which poskim bigger than Chacham Ovadiah disagreed with”…
We should have some sort of rule that if you are going say Gadol X is “bigger” than Gadol Y or that the holding of Posek A ” trumps” Posek B (except for Ungarashe yidden living in Bnai Brak)…etc. you have to also post your Gadolim ranking or Posek “top 10” listing….this A is bigger than B stuff is both silly and not especially informative since no one has a clue as to the criteria you are using and generally, different groups have different perceptions as to who is the gadol hador (not that I would know). That’s why we have our own local rav or posek to hold by, and generally we take their guidance. However, one of the great gifts of the YWN CR is that if you carefully scroll through the archives, you can always find some attribution to some gadol or posek who will hold the exact position you are hoping to legitimize.
