The fastest driver you manipulate the grip with fir different nose down attitudes. And being non meathook so that you'll see a difference with a good non meathook fade and a nose up (mildly too) stalling type of flight.
It depends on your capabilities and physique what to get. Wraith should probably be the upper limit if you don't have large strong flexible hands with long fingers. Surge SS and even Beasts and Roadrunners could work but the last two won't indicate milder nose up as much.
