I don't use a term called "upright". My shoulders turn around my spine and carry the arms/club up and back down. That angle will change depending on club. As far as the hinging question goes, it is answered here:
http://duplessisgolf.com/blog/to-hinge-or-not-to-hinge/ I don't have many down the line videos because you don't have to be concerned about positions with my method. If you learn to let the Large Muscles (Shoulders and the Body's Rotation) take control, you'll develop a repeatable golf swing. Listen to what I say in the videos and the practice drills are "key". Remember, as a Member you get a golf swing analysis, so you might send me a couple swings so I can tell you exactly what your swing needs. The elbows eventually point down on the follow through. That is when, after the ball is gone, you follow your back shoulder up and out of your tilt, to stand and face the target.
