Tell me what you folks think. Situation I strung a racket for a friend. Checked for cracks before I strung it. Mounted correctly and strung it according the manufacturer's specification (alt mains, top-bot cross). After I strung it I checked again for frame integrity. No visual problems. Strung on a neos. Then my friend tells me that the racket snaps during a hitting session after new string job. Did I miss something during stringing? Or did the racket just happen to fail because of age? The racket was pretty beat up when I strung it. Racket was a Wilson K Pro Open.
