I've been playing with Nanospeed 9900 and Arc8DX although I feel more comfortable with power and control from NS9900, but I feel a touch of weight at the head would be good. What are the closest equivalent rackets (any brands) to Nanospeed9900? I've been curious about Li-ning N50, N50II, N55, and N55II I'm thinking to get either Li-Ning, Victor or Apacs for the price factor.
