the customs you said for woman not to make mezuman is in fact documentated in the aruch hasulchan good shabas.
the gemara end of berachos says- who is bigger Oker Harim or Sinai? if you are and oker pashut you will be stronger than sinai - cause you will uproot it so what is gemara havaamena? i guess maybe since he is Oker Harim he can not find Sinai?????
I don't think that the two were grappling....
Perhaps you are referring to the joke of Rav Hirshprung, may he be blessed with long years, that the Oker Harim would be able to uproot Sinai if he could but find him! Figuratively, that is certainly correct. As long as someone is lacking a broad knowledge of the Torah, he has no idea whether or not he is correct in his logical proofs this way or that.
Thanks for sending us so many interesting points.
Be well,
