The Roddick Pure Drive will get you as close as you’re ever going to come to A-Rod’s record 155-m.p.h. serve. Got a 90-m.p.h. delivery? This could get you into three figures on the speed gun. It has the expected heft of a tournament players’ racquet, but with the huge power bonus of a stiff semi-widebody frame. If you can get your racquet-head speed up to full throttle, the strings will collide with the ball like a freight train. The Pure Drive helps impart heavy topspin on ground strokes to keep things in control, letting you rip it from the baseline. But its big power requires a signifi cant adjustment on touch volleys, which can fly away on contact for players used to more flexible frames. The difference from the previous Pure Drive is this model’s enhanced stability on off-center hits, which Babolat says is partially because of the addition of tungsten throughout the frame to increase its strength.
