Yeah, in the past I’ve done a lot of side by side comparisons of similar chips. But that isn’t even always necessary. Sometimes the difference is subtle, but sometimes it’s striking. The sound is the most noticeable trait, in my opinion. But the feel can be pretty noticeable too. I’m not sure why you don’t want me to say buttery, because that’s a good descriptor, at least for worn in leaded chips. The leaded clay just has a bit of a different feel. I think it’s softer.Do you have unleaded chips that weigh the same as the leaded ones that are otherwise comparable (THC, same rough age / wear), and you can still notice a difference? What is that difference? And don’t just say “that buttery feeling”.
