What is immediately apparent from the first look is how far apart the main strings are in the sweet spot. For example, The Speed MP, and Radical MP both have 16×19 string patterns, but string spacing of the mains is much tighter. The extra space between the main strings allows the ball to sink deeper in to the string bed, enabling more spin and power. Though HEAD has an abundance of 100 square inch racquets, what further separates the Extreme series is the thin 21 mm beam at the throat, which transitions to a wider 23/26 mm beam in the hoop.
HEAD’s new Speed Line includes the Pro, MP, MP Lite, S, and Lite models. They have updated their Graphene Touch technology from the previous generation and created all new molds featuring Graphene 360. Instead of the focus on a polarized weight distribution (weight in the grip and tip), Graphene 360 is located in the shaft and throughout the hoop to improve stability and increase energy return. HEAD made an effort to make the popular Speed Series more comfortable and solid at contact.
