It provides a great blend of power and control. It also feels both very maneuverable and very stable. It is very easy to put spin on groundstrokes with this racquet, and it is great for serves, providing a lot of power. The Speedport Blue is a huge improvement over my old racquet ƒ{ Prince's previous O3 Blue. This is the best tennis racquet I have ever played with by a large margin." - Ken, Dallas, TX
