In my experience, the tungsten balls really do much under the pros. I have Pros under all my equipment and I have found the tungsten balls' effect to be similar throughout - basically more of the same thing that the Pros do already.
I have also used the tungsten balls between inexpensive Sorbothane feet and the gear they supported with, IMHO, a mild improvement in clarity and focus.
