Comments: 10% lighter than my Ki15PSE which makes it a good quick doubles racquet, but not as powerful (may be the string difference). Will keep the 15PSE for singles and the Q15 for doubles.

Comments: The toughest shot in tennis? Serve return! I played a lefty who serves pretty big. The Q15 plowed through his serve like nothing I've ever hit with. This is a 10 ounce and a fraction racquet that handles like a feather but meets the ball like a 12 ounce + stick. The accuracy on groundstrokes is significantly better than my current stick. Because of the higher percentage from the Q15 on serve returns and groundstrokes, I suggest that this may be the most effective "game improvement" racquet you can buy. For base liners the Q15 is just might be worth a half point increase in your NTRP rating.
