HEAD Boom: By delivering ideal feedback with improved vibration dampening, players can go after the ball with confidence. The Boom Pro`s cross section features a Morph Beam design, which pairs an elongated shaft for flex and feel with a thicker hoop section for greater access to power and stability. The racquet has different head shape than the other HEAD performance frames and it is designed with a uniform string pattern to make the string bed perform more consistently. HEAD`s Graphene Inside tech remains at the 12, 9, and 3 o`clock positions, as well is within the throat to deliver stability and ball speed. With a 10.9 ounce unstrung weight, 98 square inch head, 16×19 string pattern, and slimmer beam design, the Boom Pro has all the makings of an advanced player frame, but with a little more oomph!
