For anyone else who owns different versions of the Yonex Titanium Swing power, is there a difference in the frame of the head between the SX and the SR? The Sx seems to have a slightly narrower head than the SR. Is the same case for the rest of you players out there? Or have i just banged up my racket and not know it?

I have not noticed anything like that! I shall try to verify with brand new ones and let u know!

the frame shape is all the same, but it is sure possible, that they are indeed different after stringing (depending on how they got strung and how tight), because the SR is a little "softer" than the SX.

They should be about the same. Otherwise, it sounds like sticking hairs out to say the frame is different.

Exactly, especially if you string your racquet with high tension.
