No doubt about it, this is not a whippy racquet. The weight in the hoop and the 100sq in head makes the SW seem more than is measured. I have moved over to the GP from my Prestige Pros, which are rather whippy, and I've had to adjust my take back on my serve because of this. I used to be able to just push my hand straight up and whip through the ball with the PP, but now I have more of a longer wind up and follow though with the GP. That being said, the GP can hit bombs as well as huge kicks, as long as you get it going during your toss. The GP hits some seriously heavy balls.This weekend I went out to the courts with my hopper and hit an hour + of serves with the GP. My lesson learned is that you have to fully commit to the serve you’re trying to hit. With my old Speed MPs, I could hold back in a pressure situation or just spin in a solid first serve due to the racquet. With the GP, you can’t hold back. But the upside is that you are greatly rewarded with exactly what you want. I’ve got my kick serve back and it’s never been better.
