If weight is basically static, then the smaller surface area results in a higher peak energy, the principal a bullet works on. If this wasn't true I could fire a Nerf ball through your head at the same speed as a bullet, but I can't as it will just splatter on your head leaving you pudding faced!
Improved control comes from a more uniform larger sweet spot, but it has a lower peak power. So you can hit further off the central zone but still get basically the same power, although it will be less peak power than the central zone of a smaller sweet-spot. The power distribution across the surface is represented by a bell curve, small surfaces have a sharp steep curve, large surfaces have a blunt wide curve.
The top spin effects of big racquets come from the ability to hit in the larger sweet spot, more margin for error under extreme angles of incidence, but it's nothing to do with peak power.
If you want to drive as far as Tiger, or hit as hard as Federer, do not use big racquets or cavity back clubs! But you then have to accept that hitting outside the sweet spot will have a more dramatic effect. Anyone who has used blade clubs knows this finger-breaking effect!
I'm not talking golf LP. Just what I know.
Clearly you don't!
Quote:Power is directly related to head size; a larger head will provide more power than a smaller head, all other things being equal. A larger head also offers a larger hitting area and sweetspot, which results in more forgiveness on off-center hits. Today’s racquets are offered in head sizes ranging from 93 to 135 square inches, with the most common being 97-100. Racquets at, or close to, 100 square inches offer a solid blend of power and control for many players. Generally speaking, a smaller racquet head appeals to more accomplished players seeking more control, while larger racquets appeal to beginning and intermediate players seeking more power and a larger sweetspot.

Top spin? String type, string pattern and tension far more relevant than head size. Fact. Even lighter bats allow a faster, bigger swing!
And of course no Pro is going to use a 110SQI bat or bigger - the power gain is easily offset by the control loss.
Clearly, judging by what the Pros use, 100SQI is the optimum racquet size for the elite and equally clearly that's not optimum for an old bloke.
Sampras, for example, now uses a Babolat Pure Storm Tour, a 98SQI bat, because he needed/wanted more pop!
Finals, then 4 in a row!
