Good morning! I have a customer who uses Wilson Sensation 17 in a Prince More Attack. Just recently within 1.5 weeks she has sheared the string at two different points on the racquet. I know Prince had issues with the first generation of the no grommet racquets, but the More Attack is later with the rounded holes. Has anyone else experienced or had customers experience shearing with this racquet? Trying to determine if it is a racquet issue...a fluke of mishits...or perhaps a bad batch of string. Your feedback on this particular racquet will help. Thanks.
