Has anyone playtested both the RQ iS 1 Tour and the lighter 11.0 oz. version? Other than the weight, do they play somewhat similarly? I'm asking for a friend, who has some wrist injuries in the past. She loves the solid feel of the original version, but is concerned that it is a bit heavy. I don't know if it will end up aggravating her wrist problem with a heavier racquet than she is comfortable with. She's doing a demo program right now, but the shop doesn't have the Tour Light version in stock or as a demo right now. If anyone can offer some input regarding the two and how they play, that'd be great. Thanks!
