Head Dirty Deed Racquetball Racquet. Head's back in full force in 2009-2010 with their new series of racquets. These racquets are the most powerful racquets Head has ever produced. The 165 weight is back which is what many Head fans have been looking for since the IGS Liquid Metal series. These have some of the coolest graphics ever put on a racquet and back it up with their names (Problem Child, Mean Streak, and Dirty Deed). These will be sure winners this year and going forward.
