I have not been able to notice a friction change connected to the magic line either. But I've wondered many times just what kind of changes are made possible with respect to the overall leverage by altering the midpoint of the keystroke with respect to the magic line. It would seem (on the surface) that the most consistent key leverage would result from having the capstan/whippen heel arcs meet at the midpoint of the key stroke. I dont know if I would say that would be an ideal mind you... might be better for the key to actually be more on one side of this <<middle>> then the other. Thoughts ? Cheers RicB
