Head's Popular Tour Series comes with a choice of a Graphite (GR paddles) or Composite (CO paddles) hitting surfaces. The Graphite version weighs in at 7.9 ounces while the Composite version is 8.1 ounces. It is generally said that a heavier paddle with a composite face is better for power (Force = Mass * acceleration) and that, for control, a lighter paddle with a graphite surface is ideal. Head added their new SpinOn technology to the Tour paddles in 2022 to help increase the spin. The Radical Tour GR is made for the powerful player who needs stability as well. HEAD's Graphite Hitting Surface (GHS) combines a crisp feel and more control for added touch, while the Comfort Grip System ensures a tremendous feel and enhanced vibration dampening.
