May i know which string will bring out the best of the best of smashing using AT900T and NS9900? what string will compliment for a much better control game for AT900T and NS9900? Style of Play- More aggressive player (hard hitter), defense is my strength, net play and speed is my weakness. I'm looking for a more powerful smash while maintaining the defense. Thanks for all advice.
From a general point of view, if you really are an aggressive hard hitting player with good defence, then the best string for pretty much most if not all racquets will be BG65, BG65P or BG75Ti at 29lbs and above. This is provided that your arm strength is up to par and you don't have trouble swinging a head heavy racquet (same case even when talking about NS9900). Or if you think your full arm strength is not that good then the alternative will be BG80 at a maximum of 29lbs (and below).
