BTW, ergo bars are, IMHO, a very good development that should not be sneered at.
I wasn't sneering at ergo bars, only the terminology and the idea that it was a new concept.
I'm not sure what constitutes an ergo bar today. Can you describe? That's one of other things I was hoping to learn with the original post. The last time I bought any bar was, oh, 1980, perhaps. Maybe as late as '85.
