I use this racquet (shocking, I know), and its a good stick. I like the old APD better though, as this one's muted feel takes away some of the rawness of the original.
Serves are better with the old one as well, but from the baseline, the new one trumps. I like to add some lead tape and 3 and 9 to give it some more heft as its only 11.3 stock.
If you have a Nadal-style game with heavy topspin, this stick may be for you, but be advised, its difficult to hit flatter shots. From the baseline its a beast, but it will take some time to get used to it.
Hope this helps
