I am a beginner and just wondering about the word "pop" in reference to racquets. What exactly does it mean when one racquet has pop compared to another? Does it mean you don't need to put out as much effort to get the same results? Does it just mean it's more powerful? Knowing what it means would make reading these posts more meaningful for me. No, I'm not buying a new racquet just yet - I'm borrowing one from a friend while I learn, but I'd still like to learn what I can from some of the TW forums. Thanks!
