Jim,
I'm surprised you feel so strongly!
Throughout your RFI tutorial I see many references to the term "current
balun". In a couple of places you put the term in parenthesis, or
explain that it is really a common-mode choke; but in many other places
the term is unqualified, and clearly is describing a common-mode choke.
Chapter 6 is even headed "Baluns". In my view, anyone reading the paper
could be forgiven for thinking that the correct term to use is "current
balun".
Personally I have no problem with the term; if you choke (impede)
common-mode currents, you are driving current balance.

Throughout, you insist on using the word "balun" with some qualifying
adjective. Why use the word "balun" at all? It is clearly inadequate
to describe the device in question, and is a major obstacle to
understanding.
If what we want is a common mode choke, we should CALL it a common
mode choke. Then we realize that we must understand what it does in
the common mode circuit to understand how it works and what its
limitations are. When we call it a current balun, we don't know what
it is or how it acts -- 99.9% of hams view it as a mysterious black box.
