I understand the theory and like I said I will admit if it works out that way. I am thinking the 15 extra feet of line in the air like in your example is going to catch a lot more wind and trump any mechanical advantage gained by the extra weight out side the tip.
I may be out to lunch, but when I am trying to reach out and touch something I back cast as much line as the rod can handle with a sharp pull with my free (left) hand. Also in my left hand is a loose coil of extra line that I let feed off my hand after the air borne line is maxed out. Less line in the air means more control, less chance of hitting something behind me, less chance of over powering the rod, more line speed and IMO maximum distance.
I have been wrong before, so it certainly won't be something new.
