Hi Andy. After reading and viewing many of the play tests, it seems that two of your favorites are the new Babolat Aero Pro Drive and the new Head Graphene Speed Pro. You mention that you got about the same amount of spin with both(even with the 18X20 of the Speed Pro). Just wondering how to decided which is best for me(I will demo them both) . Is there anything that would push you towards one or the other. I'm about 50 yo, semi western fh grip, one hand bh, no history of arm/elbow issues. Thanks in advance for your help.
