Recommended StringSonic Pro 17g No CoverThe YouTek IG Speed 300 is a slightly more powerful version of the Speed MP models and offers added maneuverability. Additionally, it features Head's newest technology, Innegra. Head has combined their carbon composite technology with Innegra, a lightweight, high performance fiber, in order to improve stability and increase shock absorption. This new technology combined with YouTek technology provides consistent performance over the life of the frame. The Speed 300 offers a lighter option in the MP models for the player looking for power and easier handling. The open string pattern provides easy access to spin and more pop. Although this is a lighter model, it still designed for players who like to play aggressive, fast paced games. Thanks to d3o and Innegra, stability, power, and comfort are all present and accounted for in this frame. Recommended for advanced players who take longer, faster strokes.
