I was pretty happy with my Radarlocks, but I always had issues with the arms butting up against my Kask Protone helmet. That, along with the increased visibility at the top of the lenses were enough for me to try the Flight Jackets. I have to say, I'm quite happy with the subtle improvements. The fit, weight, and of course the Prizm lens are all on point. I haven't had any issue with fogging, so I haven't used that anti-fog lever... seems unnecessary thus far.
