So today, I was hitting and couldn't seem to get any kind of pace on the ball whatsoever, it was really bad. I couldn't figure out why, and so I decided to switch racquets to see if that was it (I use the IG Radical Pro, just switched to another one of the same racquet). After I hit one shot, I was like "HOOOOOOOOOOOOOOOLY" it was so different, and I had plenty of pace again, and my shots felt good again. I went back home and measured the tension of the strings with my twisty tension meter, and they are fine. They didn't lose tension or anything, and aren't that different from the the other racquet. What on earth is going on here? I restrung that racquet only one week ago.
