Actually my backup rack is a Head Ventoris 660. 660 cm converted is 102 sqi. But when I put the face against my 95" main racket, the heads seem to be the same size.
I have searched the net a lot but am coming up with nothing.
The 630 in Pro Tour 630 refers to head size. HEAD claims the Pro Tour 630 is 630 cm2. Just like 600 in Prestige Classic 600 again refers to head size. HEAD also claims the Prestige Classic 600 is 600 cm2.
