I would have never advocated for pulling possible A grades for this purpose. This is a by-product thing, in my mind. You also wouldn’t need a response to test for vibe off the production line, at least for the purposes of this product which assumes some imperfection.
I’m not saying it’s the obvious choice. It’s obviously not or else it would be common. But, I think it’s possible and I think people would buy it. And honestly, even if it were just $130 to maybe $90, I’d probably still do it sometimes.
