The YouTek IG Extreme Pro has all the benefits of the Extreme in a heavier, stiffer version. 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 Pro has a 16 x 19 string pattern for those players looking for comfort and spin. The new ergonomic shaft shape coupled with Innegra provides less vibrations and better torsional stiffness for increased power and spin. This racquet will provide all of the extra touch, power and spin you will need for an aggressive game.
