Of course a two-hander can be hit with an 85" head. Borg, Chris Evert, Jimmy Connors all hit two-handers with wood/metal frames. 90" is already huge, PowerGame!! Jet

Two-Fisted Jim Courier used the PS orig 85. Mary Pierce did too, then switched to the RDti-70 88. ________ Lamborghini V12 Specifications

Perhaps he meant that some frames that are rated at 93 in² are actually the same size as other manufacturers' frames that are marketed as being 90 in².

Something called the Prestiges, as well... And the Kennex Type C... And the Prince NXG and Original Graphite... And the Wilson ROK... And the Volkl Tour 10... (whatever lettered 'Engine, or 'Generation' they're marketing today).

All of these are 93". I think that the reason for this is simple, Wilson, an american company wants to make a racquet with a nice round number (ie 90) while Head, a european company wants to do the same thing (is 600 cm or 93"). If you look at the numbers 3" is a very small area. So I'm guessing its mainly a marketing difference in accordance to units of measurment.

Hold a Prestige up against the Tour 90. The Prestige is actually smaller. As Blind mentioned, the Prestige is actually 89.5 sq. in. - they simply market it as a 93 because it sounds bigger, and they feel they will thus sell more of them. 10 - 15 years ago, Head marketed the Prestige as a 89.5 sq. in. frame - and it hasn't physically grown in size since then.

may i ask, what prestige model would that be...... also, are head midsize racquets that claim 93in actually 89.5? please let me know.

I'm referring to all the midsize Prestiges - Tours, Classics, iPrestiges, and LiquidMetal. The Premier Tour (terrible racquet) was listed as being the same head size (600 sq. cm.) as the Prestiges, but the Premier's head was noticeably larger.
