The Head Spark Edge squash racket double pack contains two of these stiff rackets that feature the Amplified Fibre technology (AFT). This makes for increased power & the rackets' build has used materials designed for optimal performance. The weight of the frame is 195g (6.9oz) & they have a 75.2in 2 (485cm 2) head. The head light balance means manoeuvrability is good, & the racquets have both been strung with a synthetic gut string. The stringing pattern is 14x 19 & a full cover for each racket is also included in the pack.
