How does this racquet compare to the APD, or the yonex rdx 500, or the n61 95? I have been to 3 places around me and none have this racquet to demo for some reason.(none also have the yonex rdx 500 mid either) I have read a little about it but the v-engine edition seems fairly untalked about. Hoping to get some feedback from you guys. I am a power aggresive baseline player, who uses a pretty good amount of topspin, so im not a flat hitter at all really.
