Jack sock used the aero storm gt with cortex his whole career before switching to the ezone and percept his final year . Stevey used the aero storm tour gt before Babolat tried to force him to the 2016 Vs tour which he didn’t like and went to the Vcore Sv and then later the ezone before going back to his aero storm tour in his final season. And Cechinato is still using the Aero Vs like FAA under a paint job. The frame was pretty popular on tour at some points, just didn’t do that great at a retail level.
