Along with many others I've tried to keep some semblence of my game by changing to larger racquets and different strings - type and tensions. However, I find myself playing worse with these new combinations - or think I am. Presently, I'm using the O3 blue with big banger at 55#'s but the ball is really starting to fly on me. Gets into your mind and all of sudden your not stroking the ball right trying to keep it in the court. The "blue" is a little less than 110 inches and I find it difficult to take a good swing because of the power in the racquet. Although I'm probably old enough to have invented tennis, I still prefer to swing hard and wonder if others have found the same problem and what they have done to take some of the power out of these new sticks. I went up from the mid-size Prince T3 which is around 100 square inches - maybe I should not have changed. Comments.
