Well, this past weekend, I switched rackets with a tennis partner for fun, he using my IPrestige Mid and me using a powerful Head tweener (Si 6 ?). Anyway, I noticed an immediate power drop in his shots. Surprisingly, though, I was surprised at how well I was blasting all these flat shots. I'm certain that I would struggle to hit these type of flat shots with my player sticks. For spin shots or short finesse type volleys, my player sticks were better, but for sheer power on flat serves/groundstrokes these tweener sticks work wonders. With a 107sq.in. powerful tweener there's not much thought to mechanics. Swing in a straight line and launch the ball like a rocket. I couldn't believe how easy groundstrokes and flat serves were. With a player racket, proper mechanics are much more important. This actually posed the question which I would never have dreamed of before, could I actually play better with a tweener ?? Horrors.
