Wilson NXT proved to be very generous in the power department. This kept Siobhan & her big strokes honest. She said, " My long & fast strokes fit better with polys or hybrids, so I came into this playtest not expecting magic, but I was pleasantly surprised. Despite some issues with the high power level, I found NXT to be very playable from all areas of the court. To some extent the power kept me honest because I had to control it with a lot of spin, & I couldnt get away with slapping the ball. When I switched from the Babolat Pure Drive to the less powerful Mantis 315 everything came together & I didnt feel like the power of this string was as consuming."
