Racket Tension I was reading over 2kreative's posting and I'm stilll confused. Half the people say that stringing a racket at a higher tension (20lbs or more) will yield more power, while lighter tension (15lbs-18lbs) will give more control. Is this true ? I've read other postings and some people seem to think it's the other way around higher tension for control and lighter tension for power ? If you have some insight or the right answer I await your response. Thanx.
