That doesn't mean the info isn't out there (for or against); it just means I haven't found it. If someone else has or does, by all means pass it on. I'm not trying to start an argument, so please don't misinterpret my post. I'd just like clarification.
In the book "The Physics and Technology of Tennis" the only way to move the sweet spot is to add weight.
