Lets consider Yonex Arcsaber 10 for a moment. It's a $200+ racket. Comes in 2U/3U weight, stiff flex and even balance. Lets compare it with a $50 racket that has the same characteristic. Both racket has the same isometric head, length, flex, balance, string tension, grip and weight. The only difference seems to be the material used to make the racket. Now it occured to me that both racket would play almost exactly the same. So why would knowledgeable people buy the Arcsaber 10 or other high end racket when there are $50 rackets with the same characteristic?
