The truth is that there is very little difference in power between different racquet models. A little more difference in strings, but only when comparing completely different materials, like natural gut vs. poly or kevlar. The difference between one copoly string and another, in terms of actual speed of shot, is very small, less than 1 mph.
All this talk of power originated with the racquet and string manufacturers, who have to have something with which to lure in buyers. But it's mostly BS.
When people talk about power differences between strings or racquets they are really discussing actual power - ball speed - but also the angle at which the ball comes off the strings (which is the primary determinate of depth), as well as the feel of impact and how quickly the ball leaves the strings (dwell time).
The problem is that we're not equipped, as humans, to separate the actual from the perceptual. When someone says such and such a string is more powerful than another what they are actually saying is that such and such a string seemed more powerful to them. Another player might have the opposite experience. And neither of them really know for sure.
This forum is sustained by babbling about string "power", so you can expect some nasty responses to this post. But just pick a string that feels good and allows you to hit the shots you want and try not to get caught up in illusions of powerful equipment.
i tend to agree that there is not that much difference in power, however control is the key to power.
i play tested the 4G with a heavy, powerful racket: the great control of the string allowed me to swing as hard as i wanted which created a very heavy/high powered ball.
i have tried other polys that did not have the same level of control, so the ball i could hit was not as strong.
players with more moderate swings will not reap the benefits.
