Snap Back?
For several years, tennis players have been told that some string material will “snap back” during impact with the tennis ball, creating an additional rotational force on the ball. This may be true for some period in some cases, but what if the string does not “snap back”?
Now what?
No Snap Back
If this happens to you, we suggest you do not move the string!
The string is in this position because your stroke sent it there! It just didn’t snap back.
This lack of snap-back creates a very nice string spacing that allows the ball to have greater intrusion into the string bed, more dwell time, and possibly more rotation.
This client strings his racquets frequently due to tension loss that may lead to what we see here. If you want to, or need to, continue playing with this racquet as you see it, try it without moving the string back into position.
Where is my power?
Tennis players want power, control, spin, comfort, durability, and fun!
Well, so do we!
We collect data to contribute to your greater enjoyment of tennis, so we are including this video to address some questions about power!
Because we do not know how you are swinging the racquet, fast, slow, or in between, we must rely on data (numbers) to help us help you.
