I have just ordered the Radar EV.
28 individual pieces, the looks and the cycling specific nature of the Jawbreaker put me off.
As I understand it the Radar EV addresse the TT position issues of the original version. If you look at pictures you will see that the lens is taller between the nose piece and the top of the frame, more like the Radarlock XL.
I’m currently using a set of Radarlock XL glasses and was looking to get another but Oakley are no longer offering a polarised iridium lens in the Radarlock XL.
Due to travel commitments I won’t get them for a week, but happy to report back in comparison to the XLs which I think are excellent.
