Just joined a couple days ago as I was digging up much info on the Radar, Jawbreaker with Photochromatic lens from this site. I have about 9 pair of glasses mainly M Frames W/Heater lenses and a M2 with the sweep. We were in Italy early fall this year and I got a good deal on Radarlock Photos in Path lens and I really like the way this lens works. I went ahead and recently purchased the Radar with Photo Pitch lens because it is a taller lens which will keep my eyes from watering in the cold Canadian winters. I have also sold a couple M Frames to one of the local club members. Hoping two pair glasses will fulfill most of my needs. Not saying I wouldnt buy another set of glasses but for now this is good.
