The Head Spark Elite squash racket double pack is comprised of two of these rackets that have been stiffened by the Amplified Fibre technology (AFT). This means the power potential of these racquets is increased, & they both have a 75.2in 2 (485cm 2) sized head. The frames each weigh 190g (6.7oz) & feature a head light balance that makes the racquets more manoeuvrable. They both have a 14x 19 string pattern pre-stung with a synthetic gut string & come with full covers to protect them off the courts.
