Congratulations you're a terrific troll. You've kept this going way longer than intended because I thought you were going somewhere with intellect. In the end, you keep making stuff on the spot and bringing up stuff out of context as a distraction for a lack of sources. That'll do troll. That'll do.
Yes, we know it's all about the technique. But if your racquet collapses every time you volley..you need to add some lead to it...
