The Aero Shape technology in the RQiS 1 Tour XL 100 gives the frame a thicker profile in the head and a thinner, more flexible shaft to promote better power without sacrificing any spin or control. Playtesters certainly found a high level of power with this racquet, and a comfortable response on shots hit in the sweet spot. Serving was particularly noteworthy as many testers felt they could crack huge bombs with this stick. Putting a decent amount of spin on your shots was also not a problem, but control from the baseline wasn’t quite as reliable. Volleys, on the other hand, were much more dependable and drew the highest praise. At exactly 10 ounces it’s lightweight and easy to handle, yet the head heavy balance gives the racquet plenty of backbone. If you make contact off-center there can be a bit of twisting, but otherwise it’s not a problem.
