I just found that the badminton rackets of Yonex are separated by different series, including Nanospeed, Arcsaber, Armortec, Cabonex, Muscle Power and Basic. What are the characteristics/advantages of those badminton rackets in those series? Which series of badminton rackets should the junior badminton players choose? Thanks!
Generally NS series are head light, Arc series balance and AT series are head heavy. But there are many exceptions. As ryim mentioned, search on the YY website or also use the search button to find info (on a specific model) here at BC. For your second question, to me it really is not a big matter what racket to use for junior/beginer player.
