Bought this as a replacement for a 15-yr old Pro Staff 5.7 EB (even balance). This racquet is slightly heavier, about 3/4 oz, but is 8 pts headlight (balance point about an inch closer to the handle - so they don't feel very different in terms of swing weight.
But, this raquet is absolutely awesome for serves, and stability during volleys reminds me of the pro staff 6.1 90.
This racquet definitely has more power than my older pro staff, which wasn't one of my goals. However, this racquet seems to produce more spin, and I honestly feel that the control of this racquet is outstanding for the power it delivers.
As with any racquet, it has to suit your game - which you can only tell from a demo.
I would definitely put this on a list for someone looking for a more power and spin in their ground game. I still need some time from the baseline to really adapt, but so far I am very pleased with this racquet.
PS - strung with Wilson Savage Duo at 55lbs.
