HEAD’s CST optimizes the paddle’s torsional stability of even the lightest paddle in addition to reducing vibrations. The specifically engineered weight distribution system results in optimal precision with great feel and touch.
The ball explodes off this racquet which can take a little getting used to at first and makes deadening hard shots a little harder. It also has a smaller sweet spot then other racquets I've used. Nevertheless it makes long shots easier and more accurate since less force is required. So it is kind of a trade off. It definitely is a high performance racquet for 3 plus or better players.
I found the 5" grip length to be no longer and even shorter than the 4 1/4 grip length racquets I have used before.
