tora umada-
I am just curious whatdid your posek say bsheim rav elyashiv ?(especially since he supposedly heard it directly from rav elyashiv)
can you fill me in?
i know many different claims bsheim rav elyashiv.
(including hearing from someone reliable that when asked if he wrote a teshuva that says it is a problem of min kanaf, he answered that there is no problem and he never wrote such a teshuva and he doesn’t know who did)
one thing vadai is that Rav MM Karp who is a talmid muvhak of Rav Elyashiv ztvk”l wears techeiles.
