I avoided positive red in the past because I did not think I would like the red and never looked closely at them in person. I recently got a pair of M2 frames in +red polarized and really love the way the color looks on them. I also got a pair of +red heaters for my regular M frames. I have read some posts where people say they prefer the look of the 'old' +red. I tried to do some searches but could not find much information or any images. Can someone explain or show some pics of the differences in the current vs older +red iridium? Thanks!
