Hi, my current setup is a Babolat Pure Drive using and hybrid string. Main is VS gut at #54 and Cross is RPM at 52# and love how it play. I recently ordered a new racket (Wilson Prostaff 97L) and want to use the same hybrid string so my question is... Should I keep the same tension or drop it a couple of pound because of the head size difference? Pro Staff is 97sq and pure drive is 100sq. Thanks.
