I re-strung yesterday using CP at 40 / 37.5, which gave me a racquetTune reading of 40.6. I was playing today with the racquet strung in LO mode, until right at the end my partner asked if he could have a hit with it. So I had 10 minutes rallying with the CP string bed. The first note was that it felt slightly tighter, though that's possibly because the LO bed had broken in a bit. The most noticeable observation though was that the ball was coming off the string bed at a higher trajectory; my balls were clearing the net a good two to three feet higher than they had been. Overall, contact felt more 'solid' if you will; whether it's in my head I don't know, but I felt I had more control over where the ball was going. My mind my change as I continue to play with them, but as things stand, I definitely lean towards the feel of the CP string job.
