Yeah, I was wondering where you or anyone else mentioned anything about fast hips. I even read back through the thread to find that little nugget. No luck. Interesting...I don't necessarily disagree with any or all of that out right. Because the handle in the whip analogy will also be the slowest moving part in that system as well. That's why I "Liked" your original post, because you also said, "The brakes matter more than the engine", and that too is correct.
Look how close we are to coming to consensus as I mentioned earlier when talking about "sodas".
