As TW shows, other Blade V7 models has ditched countervail and returned to old graphite+basalt material.
Only Blade SW104 Autograph V7 keeps the countervail+graphite composition.
Plus, as we can agree, the RF autograph keeps the same material all the time, and it's the real hairpin that RF has been using.
So does this mean that Serena Williams has really changed to the CV version at some point and has really been using it? My brief guess is yes... otherwise Wilson could just make SW104 in...
SW104 Autograph V7: still with countervail, so..
