I just received a brand new demo of the Flexpoint Radical Tour. But it looks huge, I believe it's almost just as big as my old I Radical OS. My current racquet is the Head Prestige Classic so maybe I'm just a little confused, thinking the racquet is really that big, but on the other side, my Pro Tour 630 was just slightly bigger than this my Prestige. Considering the difference in square inches, the Radical Tour should be much larger or both the Pro Tour and Prestige Classic are smaller. So How do I measure this?
