Been using a Babolat PD 110 cortex for a few months now (previously using a POG OS). Love the lightness, balance, forgiveness, feel, power & spin of the racquet. My wife has the original 110, which I also like very much, but somehow the cortex has a more damp & solid feel (and it at least feel more comfortable). With a hybrid string setup with luxilon rough in the mains, this racquet can generate loads of topspin, with easy access to power. I was also surprised that quite a few advanced players like the 110. Of the oversize racquets out there, the Babolat 110 seems to get alot of love in capturing the spirit of its smaller brethren without giving up too much. Still, I am thinking there is a point where the APD or PD would make more sense. I am a 3.5 now, but have the goal to progress to 4.0 or 4.5 over the next few years. I am thinking to switch to an AeroPro Drive or Pure Drive, for better control and possibly greater spin. It might also force me to be a better ball striker and give me better feedback on mishits. Maybe I can get even more spin? Anybody out there have experience with the 110 & either the APD or PD? What would you give up and what would you gain? Love to hear some feedback.
