A guy at my club let me use his Tour 10 today and I loved it. It felt a little lighter than the specs with a very comfortable stringbed. The upper-hoop delivered no where near the power-drop off I expected given the flex. [It was strung 58lbs with gut and this may have contributed to the lively comfortable feel]. The weight seemed right for the clay, the off center stability was impressive, the control-power ratio was wonderful --a few swingweight-pts lighter would have allowed for easier out-of-position forehand whips, but for the most part, preparation against heavier balls was suprisingly easy. I was having some trouble cranking serves and I'm not sure if it was because I needed something slightly lighter to generate more headspeed, stiffer for more power or if I was missing the sweetspot. Overall, though, great frame. Does the pro #1 play similar to the Tour 10? Would you say that it is as comfortable in terms of the low amount of shock/twist & torque found in the T10?
