I wonder if a homemade version of these could be made? I have numerous old racquets lying around I wouldn't mind cutting off at the throat. I'm reasonably handy making homemade exercise gizmos (I made my daughter a vertec out of pvc and a volleyball spike trainer I attached to our basketball goal) so I bet I could make something pretty close for a lot less than $199.
I wonder what could be attached to create a device similar to a Sweet Spotter. Anybody want to speculate?
Thanks TW for the version reversion and Xenforo FTW!
