Racket - Maintenance?
I have a few questions here...I've been looking for an upgrade over my cheap wallmart racket. I found a few nice rackets but I noticed the strings not alligned/straight. Is this the norm for pro rackets...do they have to be adjusted/straightened by hand after each volley? Is there additional maintenance or stringing involved with these rackets? I'm a bit confused regarding this b/c the racket I have has been used many times and the strings have not moved at all.
