Hullin 99: The Taste of the Gid HaNasheh (or lack thereof)

More on nullification of a non-kosher food in the greater quantity of a kosher food. In accord with the view that said 100x more than the non-kosher food was necessary, but the idea that it should be 100x seems off to Abaye -- at least if the claim is that that quantity is necessary for all prohibited food in this kind of mixture, but that's illogical. Also, do sinews contain flavor? Do they impart flavor?
