Avi,
“‘Rav Shteinman was obviously not feeling well. ”
Why? He made more important decisions at that time for the Klal than others do in a life time! His mind was crystal clear until the last days. Especially he was extremely careful about every word uttered. If it was ASSUR it wouldn’t even cross his mind to say so. Thus, not “feeling well” is a way out…
“In any case, he is a daat yachid.”
Who decided that the “rabim” holds the other way, just because one quoted a couple of Gadolim saying something does not mean it is final, nor can it be applied to every case.
