"Experience with the APDC probably depends upon what you are used to, how you play and what it's strung with. The APD and APDC sort of seem to dictate the style of play you use because it's so easy to add spin and power to hits if you are a full swing power player. If you're not open to adding these concepts to your style of play, neither the APD or APDC are probably the racket for you.
FYI, I'd used a APD for a couple years until I goofed up a string job (forgot to tighten the racket clamps) and a small crack appeared on the inside top rim, so I decided I'd better get a new racket before my APD broke -- choosing to upgrade to the APDC this spring (2007).
Strung with TopSpin Cyberflash 17 @56, or Big Banger Ace 18 @54, the APDC provides plenty of power and control. Power serves and hits of most every type (spin, flat and mis-hits) go pretty darn near where I think they are going to go when they leave the racket, a bit finer touch than I feel with the APD. IMHO, the APDC is a modest step up from the APD performance in most every fashion.
BTW, my slightly cracked APD racket still works fine - my son borrowed my APDC and won't give it back, so I'm back to using my APD with the slight crack.
Also, I've tried a variety of strings in my APD, the Cyberflash 17 or Lux Big Banger Ace 18 make it a very nice racket. Some other strings I've tried made my APD a very terrible uncontrollable racket. I suspect the same sensitivity to string choice holds true for the APDC since the APDC and APD are pretty similar in many respects.
Finally, I occasionally get asked by fellow players if they can try my racket. Almost without exception, they find it surprisingly powerful and controllable, quickly adjusting to it's pop and accuracy. I typically try using theirs during their demo of my APD or APDC. Most rackets others use seem like dead sticks by comparison.
In my experience, the lone exception is Roddick's racket, which is a cousin to the APD or APDC. Roddick's racket is a notch heavier, which may provide a little more stability on off center ground strokes and net play. If you've got the arm, apparently it can provide a faster serve. However, for me, I can serve faster, get more spin and maneuver faster at the net with the APD or APDC than with Roddick's racket."

I think it was pretty informative.
