The Pro Open BLX has a blend of power, control, comfort and stability that suits a wide range of player types, from baseline bombers to serve-and-volleyers. It has a sweet spot that rivals the expansive hitting areas of frames with much larger heads, but without the tendency of oversize racquets to twist on off-center hits. The racquet has Wilson’s new BLX technology, which mixes fine-grained volcanic rock, or basalt, with its existing strengthening mixture of carbon black, graphite and silicon dioxide, which was introduced a few years ago in its [K] Factor racquets. This construction produces such a comfortable feel that it renders vibration dampeners obsolete yet doesn’t compromise on the feedback you need for control from all corners of the court.
