So far I have been readind the threats and realise camparison often made only to the stiffness, weight and etc. So, what about the frame? Well nowsday Yonex produces rackets with thin frame like what we can see on Yonex VZF as compared to other brands of racket. However, somehow, it gives me a feeling that it is less solid and not durable (I don't refer specifically to VZF but most of the models of Yonex). What do you think?
