I've been doing some serious experimentation with strings and tensions since purchasing my RDS002T's. I've heard there are two schools of thought with string tensions: 1. String crosses 3lbs lower than mains. 2. String crosses 4-6lbs higher than mains. Which is better and why? Also, I did two different RDS002T's at the following tensions: 1. 62m, 59c (16g Technifibre X-One Biphase) 2. 54m, 52c (17g Technifibre X-One Biphase) For some reason, racquet #2 felt more boardy and gave me less control. Why if the tension is lower?
