We certainly have had an interesting discussion about this and probably all have learned from it. I admit I haven't studied aerodynamics for 30 years but 30 years ago I wanted all the answers and found most of them in books. Asking fellow pilots usually ended up in multiple answers, most being wrong.
Captains wanting the flight attendants to move to the front galley to save fuel because the tail was dragging enroute, etc. One chief pilot insisted you had to hold downwind rudder when enroute to keep from weather vaning into the wind. In a discussion like this everybody gets their input and usually the truth prevails benefiting everybody. Thanks to everybody for contributing.
