“When Nadal hits the ball, he hits rockets,” Carter explains. “With this [99S], it’s like hitting balloons. When Nadal hits it, the ball goes straight through, but this ball sits up.”

Translation: You'll get plenty of spin, but the ball may spin up at a higher vertical angle, which could give your opponent more time to hit the ball back. Against a casual player, this effect might be negligible, but against a pro it could make a big difference.
Just wanted to point out that the "sitting up" Carter mentions is a matter of trajectory, not spin. The OP, Drakulie, found that, in his hands, the 99S generated more spin and more pace than the APD. It also consistently gave him more net clearance, which means it produced a higher average launch trajectory. A high trajectory means a higher bounce. But we all know that trajectory can be changed. We can hit super spinny forehands that pass an inch over the net and land in front of the service line, or we can hit super spinny forehands that clear the net by ten feet and land on the baseline. That's up to us. The 99S most likely does rebound the ball at a higher angle than closed-patterned racquets, but trajectory is still something under the player's control. One way is to close the racquet-face, which lowers the launch trajectory AND generates even more spin. So if Drak was hitting with more speed and spin high over the net, he could hit with even more spin lower over the net. A fast shot with more spin on a lower trajectory is not a sitter, it's a heavy ball. This might not work for all players - conservative grips might make it tough to close the face, etc. - but I wouldn't write off these frames just because a high-level player wasn't able to make them work for him during a short playtest. The strings might have also been too loose, which would raise the launch angle even more - the ESPN piece doesn't say how they strung it.
