Due to some instablilities in my Extreme Pro's (08) I've decided to start demoing a few racquets. Though I need some suggestions on what to demo. So far I have ordered in the Pure Storm, Prince Graphite 100 and the Kpro Tour. My playing style is around a high 4.0 to a low 4.5. One handed backhand with a nice amount of spin on it. And depending on the shot I can either flatten or hit spin on the ball. I love playing sharp angles and I rarely come into the net. (Though my coach always told me I should serve and volley) Strong serve depending on weither or not it's flattened. Thanks. All help appreciated.
