I won't even share weisswursts with my own family that I buy from a German butcher shop in Frankenmuth, and that's basically local. I wouldn't dream of trying something different out of a favorite I brought back from another country.
You can get weißwurst in Michigan? That's amazing! Berlin is too far north of the Weißwurst-Equator (https://en.wikipedia.org/wiki/Wei%C3%9Fwurst%C3%A4quator) and I don't even know places that do them properly here! (Ok, maybe if I looked hard enough there probably is one...but I am very impressed!)
