I hit with both frames last night, I played doubles for a couple hours, so I was able to serve with the frames, hit groundstrokes and spend a good amount of time at the net. A lot of people noticed the fact that I had them, that bright blue color (which I am fond of, fwiw) really stands out on court.
I play with heavy frames to begin with, so I was more drawn to the Roddick, though I made sure to pay some attention to the regular PD as well. Both were strung with Babolat Addiction at 61#. As a side note, addiction is a pretty nice string...
My initial thoughts were positive. The Roddick was a monster on serve and was great off the ground. Surprisingly, my touch and feel at net was pretty good and I was working a nice backhand slice that was quite effective. I got really nice bite on the ball and I used that to my advantage. I wasn't really expecting to like either of these racquets, but I thought they both had a nice feel to them.
I will say that these frames seem to be the closest thing to the original Pure Drives that I have hit with. To me they felt better overall than the older models...They have that crisp feeling that I've missed with a lot of the Babolat cortex frames that tend to be a bit more dampened (but not in a good way...). While this is a very, very quick reaction to the racquets, overall I think they will perform better overall than the previous models.
As I get the chance to hit with them more, I'll post more thoughts, but for now, hopefully this bare bones feedback will suffice.
