The played very different despite having the same curve (and the same MgR/I). I am not only referring to ball trajectory, but also the felt racketheadcontrol. The polarized one has a whippier feel than the other one.
The equivalent mass is the same for both rackets, but do you know why they play so different? I think I know why just by experience, but it would be great if there was a scientific explanation.
You measure SW in the plane perpendicular to the stringbed, but your swing is not in that plane.
The higher twistweight frame has higher SW in the plane of your actual swing, so effective MgR/I is lower for that frame.
