According to TWE averages the all black RF97 unstrung is:Looks like he plays with an overgrip. Not sure if the 360g includes overgrip? (the pics from the stringer don't show overgrip, but the pics of him playing do show overgrip).
All 4 of my RF97A's weigh more than 355g strung without an overgrip (which would be equivalent to his 360g minus his 5 g at 3&9). Maybe he does some custom handle work to make it more head-heavy?
Or, maybe he hand-selects some very light frames from a production run?
With the 97S it seemed it was trying to replicate his custom 93 specs in a larger head size. It appears he is now branching out to different specs as well as string pattern and head size.
