A short audio clip from a shiur by Rabbi Asher Weiss. The full QA session can be seen here: https://www.yutorah.org/lectures/926624/
Here’s the transcript:
Participant: I know the Rav’s stance on Techeiles is we shouldn’t wear Techeiles. The Rav is going into more of an explanation —
Rabbi Weiss: I never wrote we shouldn’t wear. I wrote we don’t have to wear. There’s no down side to wear Techeiles. But I don’t wear Techeiles. Because to me, to do something it’s not enough that there’s no down side, the question is do we need to wear Techeiles or not. In my opinion we have not found Techeiles, and I doubt we will find it until Moshiach comes. So I made my opinion very clear in Sheilos v’Tshuvos Minchas Asher, that I don’t believe in what is considered present-day Techeiles, but anyone that wears Techeiles and he asks me should I stop, no reason to stop. There’s no down side.
Participant: [Inaudible]…It’s not an issue of Bal Tosif?
Rabbi Weiss: No, it has nothing to do with Bal Tosif. Any mitzvah or chumrah that you perform, based on a chumrah – maybe this is what we should be doing – would never be considered Bal Tosif.
