For example, a long dwell time might be a disadvantage for returning a spinny serve as the serve has more time to "take hold" on the racket face. 然而，停球时间偏长或适中的套胶常常是大多数选手的首选，尽管他们中的有些人可能要为此而作出一些技术上的调整。
Trying to return a sidespin serve will be a hair-pulling experience for a beginner if he/she uses an overly spinny rubber. 如果一个初学者使用一块旋转速度都非常高的胶皮的话，那么他在回击侧旋球是会觉得尤其难对付。
