Little off topic but...
Demo'd the 2012 Roddick Pure Drive last night in my league match.
That thing is a monster. I own a APD GT (that I don't use much anymore) and the Roddick felt softer.
Seemed to be an easier swing than the APDGT even though it's heavier.
But during the second set balls started flying on me. Maybe it was the synthetic setup since i'm used to full polys.
