My daughter is 10 years old and has been using Yonex EZone Xi Lite for about a year. I am thinking of getting the Yonex RDiS 200 Lite MP for her (she may be able to use it next year the earliest.). Should I get it now or hold off until she is ready? The reasons I am inclined to select RDiS 200 Lite MP include: 1. The power level is medium as per the spec; 2. The head size is 98 sq in, I hope she gets used to smaller head size early on; 3. Low price, $80 a piece; Any opinion if I should do it now or wait to next year when she is really ready?
