Hit with it for the first time today, and on groundstrokes it was amazing....after a 10 minute adjustment period. Im used to taking big brushes at the ball, but here I had to get the racket ready ahead of time, and just take a deliberate and measured swing through the ball and great results followed. Never has it been so easy to hit a one handed backhand! I just get the racket ready, took a smooth easy swing and BAM! Awesome. Serve was very tough, and have read that you cant be whippy and get good results. And the ridiculous stability combined with low power allow me to returned the hardest groundstrokes with interest. I cant wait to hit more with it!!
