I would not agree with this, although I can see why you feel this way. Narrow is more aero (=why narrow wheels still rule at low yaw); lower is not always more aero because people can't really change the angle of their lower back. Lowering the front end doesn't change that back angle -- and often other stuff rises (e.g., head/shoulders) to offset it.
If one can ride narrow, they probably should (from an aero perspective); if one can ride lower... MAYBE they should.
Zipp SL70 = stiff. 3T aerobars... pretty flexy.
