Included in this double pack are two Wilson Whip 155 BLX squash rackets. With a 75.5in 2 (487cm 2) head & an open 14x 18 string pattern, these racquets offer increased spin & power potential. The rackets are fairly lightweight at 155g (5.5oz) & have a head heavy balance for more stability. Power Hinge technology optimises the string bed's movement so that the sweet spot is bigger & hitting with more power is possible. BLX decreases vibrations for better feel & feedback, & the Sensation Strike 17 string with which both rackets come pre-strung encourages more power & precision. The string pattern is 14x 18 & both rackets are supplied with a protective 3/4 cover.
