Tom Stites Inertia Quotations

I think there will come a day when people will purchase drivers by ball performance and not the hype or numbers written on the club. Driver true-loft performance is a synergy of factors. Only the ball flight can tell you the true dynamic loft -- and that is a mixed function of measured loft, face angle, center of gravity, moment of inertia top to bottom and face roll.

It's like making figures out of balloons. You can fill a balloon with air and shape it to be a pretzel, a donut or a hot dog. Each will have a different moment of inertia and a different center of gravity. By changing the shape of the balloon, you change the physical properties of the balloon.
