I have a pb10 mid+ that is 18x20 with NXT. I had to swing out a bit more to get the pace I was used to on my other racquets but was then rewarded with a bit more kick and topspin. As I played with it more, the swing speed started to come easier as I was gaining confidence. The spin and ball action continued to reward proper mechanics. Very good control and touch. A bit challenging for me to keep pace on my serves and I know I need to give it more practice.
I wanted to try the mid but haven't had a chance to. I would think you would get more pop. Happy testing!
Married into a tennis fam-trying2keep up after4knee surgeries. I almost have more racquets than my wife and in-laws (don't tell the wife)
