Ok, thank you! That's a relief. I'm one of those who loses some sleep over details like this. You know, like questioning why Benedetto goes through the trouble of radiusing his tailpieces, as if that's the key to achieving superior tone. But yes, looking into it more, it appears a flat radius at the tailpiece is quite common. And I've just come across some makers who build the tailpiece so that it can roll to either the bass or treble side depending on how much downward pressure you want to a particular side. Very interesting stuff!
