I love the Black PD, especially the Roddick version. I have 1 PDR, 1 PD customized to the specs of the PDR and 1 PDR+.
2 of them have natural gut in the main (Pacific tough gut) and a copoly in the cross: MSV Co-Focus 18, better for sawing into the gut and the other MSV heptatwist 17 (better for sawing

).
I really like the softening hybrid combo. It plays softer/with more dwelltime. A bit the plushy feel of a radical. I really liked the radical pro (or MP) for it's unique plushy feel. But I returned to the PD because those are special regarding spin/power! They also look very cool, but I look cool by myself

so that's kinda bonus
The PDR+ came strung with Solinco Tourbite 1.1mm strung @25/26kgs. That's really a spin beast. The sound of it is awesome. But it also seems like you can hit as hard as you want and the spin will help you with crazy angles or fast-diving-inside-the-baseline balls. It does have less feel than the other 2 setups but it sounds crisps and the sound and spin are addicting... I have no problems with the extra 1/2 inch of the PDR... strange but I adapt automatically when playing and switching with the racquets. Maybe because of the large sweetspot? I don't know it isn't an issue so I'll leave it to that.
I would recommend one of these setups to you, also depends on what you're looking for. I can't decide... I'm continuously switching: on gives me more feel/touch and also the power/spin I want... the other is when I want to release the hard hitting spin beast on the court! (so also less accurate/control). So it comes down that mostly I prefer the hybrid for doubles and the beast for singles...
I'm looking forward to your experiences because I have tried many racquets but keep returning to the PD, it has something unique that fits my game apparently...
Currently playtesting the Graphene Speed Pro to experience the spin and control... still trying to love it...
