A number of years ago I tried a friend's Harrow Vapor and for some reason I instantly liked it. Now that my last racquet broke, I figured it would be the perfect opportunity to try it again.
The first thing I notice is the balance, and the rigidity of the frame. Now, the frame is just a little smaller than other similar shaped racquets (and certainly than the water-drop models), but with the stiffness, when I hit the ball in the sweet spot, I just feel everything comes together and I hit a clean, precise and powerful shot. And I love that feeling, and the quest for that feeling every time!
