The boomerang effect (and how to avoid it): Speakers tend to use arguments that persuade only themselves, rather than the subject to be persuaded: his audience. It's similar to sympathy in argument by emotion, only this case, you need argument by logic. Whatever you're choosing is very "'advantageous' - to the advantage of the audience"
Babbling: Aristotle argued that arguers tend to repeat themselves over and over, revealing fundamental principles on which your argument is based.
Commonplace: determine what your audience is thinking, in order to appeal to their common sense. Start by defining their position and relating to them, in order to sink them in your argument. They are always rules of thumb instead of facts, as they define an individual and help determine their self-identity and what will lead you to get to their commonplace.
"Anadiplosis: Builds one thought on top of another by taking the last word of a clause and using it to begin the next clause." This appeals to logic, is a great argument strategy.
Rebuttal through commonplace is most effective, because when you walk away vehemently from the commonplace, there's no ground for persuasion left.
You defined all the terms very well but I must confess, I was kind of waiting for an example that brought all the definitions together. That didn't happen, obviously.
