Question: What's the best string tension for more power?

Answer: Generally, if you string at the lower end of your racquet's recommended tension range, the same stroke will make the ball fly farther. Lower string tensions generally result in the ball rebounding off the string bed with just a bit more energy, but this effect is too slight to make the ball fly significantly farther. The United States Racquet Stringers Association recently published a study that concluded that the reason lower tensions hit farther is the result of the ball remaining on the strings longer as the racquet is swung upward.
