iso VF vs other models

[Todd]

does anyone know how the iso VF line generally measures up with the other rackets that YY makes?
tahnks

Apparently the VF frame technology is supposed to reduce air resistance and allow tighter tensions. My friend owns a VF model of the Iso 85. And he gets his tensions at a 22lbs minimum. Besides that i'm not sure..... But i wouldn't spend the extra cash on the VF model.

reduce air resistance?
i found something about shockless grommets. does that sound familier?
and what difference would that really make? i heard that it would allow the strings to bend and flex on the frame easier and with less loss of power. i'm not too sure.

thanks

I have no idea at all, sorry. Maybe Kwun can help. I'm not to familiar with the VF model rackets. I've never tried 1 myself. Sorry...
