I played with the o3 white this weekend and found two problems, lack of pop on serve and lack of control on groundstrokes(too much depth). I strung the frame with my usual wilson synthetic gut at the maximum tension, 63lbs. I always use that string with my hornet midplus and I have no control problems with my hornet, even at much lower tensions. It is clearly a problem I am experiencing with the o3 white. Has anyone found the same things with the o3 white? I tried putting lead on the frame and on the handle and that helped the serve but I still hit wide and long on groundstrokes.
