only got to hit for 30 minutes today but here is my initial impression based of my normal mains of Pro Hurricane Tour.
Normal Setup is:
Pure Drive GT
PHT/Addiction or Xcel crosses 60 lbs
Power: Definitely more power than PHT. I string PHT on my Pure Drives at 60 and so I did the same with this. I was hitting the balls pretty deep but right on the line or over it. I need to string this a few lbs tighter next time. Serves were a little more poppy than normal.
Spin: Very spin friendly. I noticed that on my serves I was able to kick it out a little more. On my backhands I usually hit pretty heavy topspin and I had to flatten it out a tad as I was hitting the tape more than I usually do. My hitting partner noticed more topspin on my balls than normal.
Feel: Did not notice any difference on this than PHT.
Overall I was impressed with it and will definitely start playing with this over PHT. I still wonder about tension loss though.... But being a stringer and Babolat sponsored I wont worry about it to much!
