Thanks for the link but I see no such evidence here: http://sonicboomgolf.com/PhilMickels...eSwingKeys.php
No evidence here of what you speak.

Breakdown of the materials of the clubhead is more likely to be due to faulty components of same. Do you remember when John Daly first appeared on the scene and talked of the number of clubheads that he had broken, and the move to Kelvar if memory serves me correctly. None of that today. Maybe someone here with math/physics can calculate the effective momentum of the clubhead at impact and compare it to the mass of the golfball (it has no momentum, being stationary) and show just how wrong your claim is.

The golf ball has no momentum, but it has inertia that the clubhead needs to overcome. And the clubhead loses speed when it impacts the golf ball. I thought that was pretty much universally understood (as far as golf nuts are concerned); I'm not sure I understand what you're disputing.
