I have an RDX 500 MP... and note that on the TW website it ia 332g & 8-points head-light. Now it says on my racket, its 310g, and it really does not feel 8-points head-light.... more like 4. It doesn't feel 332g in weight also. It also says on it the balance point is 31cm, and on the website they say 32cm. Can anyone explain this?.. surely its not just manufacturing tollorances?
