I have played both frames very much this summer in a test for the swedish tennis magazine and I fell in love with the IG Extreme Pro so much I actually have ordered it to use as weapon during the indoor season.
The Rad Pro is very very soft in the flex. It has good power for such a small headsize and flexible frame and the touch is outstanding.
The Extreme Pro 2.0 is very crisp in the feel but they have also managed to reduce a lot of the vibrations. It has such a great feel, power and spin but at the same time a really good control for such a high power frame.
No Guts, No Glory
