I have been able to demo the Speedport Black and the Speedport Tour. I was able to control the ball more with the Speedport Black which may have been because it is stiffer or perhaps the strings were tighter. Does anyone have any experience with the O3 Hybrid Tour? On paper it looks like it may be more similar to traditional rackets (which I am using now - Prince Graphite II). I am looking for a racket with similar response but better for the arm and shoulder. Thanks for any input.
