No, this time Yonex adapted 2 isolated system to evaluated rackets.Originally Posted by nibaxiang
The new graph only tells the head-heaviness. The Y-axis only tells the position of the racket ( Grade) . There's a racket introduction beside the graph ( the graph you see here is not complete) and the Y-axis is to match the position of the introduction of rackets.



weren't you the bloke with the brandnew NS9X?
