Correct. It's why the measured stiffness of a frame will differ between a grip 1 and a grip 5. Because the foam stiffness is also measured as part of the frame pull on an RDC.So L1 grips have a tiny amount of this foam?
graphite handle size (hairpin?)= always the same?
I’d be curious to know how much a replacement grip could shift it. The RF vs the PS 97 for instance have a different stiffness and the RF has leather as well.Correct.

It looks like racquet autopsy. Now I see why Chaho was so popular.@daniel2015
As long as the wilson handle doesn't have a version Amplifeel or Airshell (I don't think any 6.0 did) I think you will find the shaft under the foam to be the same size as another racquet of the same model but different grip size. Said another way with a given model Wilson modulates grip size by foam. You'll likely have weights in the foam that you could possibly hit depending on how far down you go but otherwise I would expect the handle to be composed very similar to this one that was dissected: Pro_Tour_630, Feb 19, 2009
