Introducing the heaviest member of the Boom family! Named the Boom Pro, this racquet combines surgical targeting with easy power and great feel. It also gives you a tad more stability and plow-through than the Boom MP, but remains fast enough for the aggressive all-court player. Technologies include a Morph Beam, which combines an elongated box beam shaft with a more powerful construction in the head. The Boom Pro also packs a wider more responsive contact zone in the upper hoop. The result is not only a more expansive sweetspot, but also a more generous spin-window at the racquet's maximum leverage point (think heavy ball). In addition to Graphene 360+ (which helps with power and stability), this racquet includes a uniquely flexible Auxetic construction in the yolk, a feature that optimizes ball feedback according to impact location. On the court the Boom Pro not only delivers the quick handling, easy power and spin-friendly precision of our favorite modern player's racquets, it also feels great at impact, and it does a good job absorbing and redirecting higher levels of pace. The fact that it plays great right out of the box is a nice bonus. Stiffness was changed from 67 to 66 due to additional samples measured
