Cut by InfinateHero from Big Taco fire iridium replacement lenses. I had to do a little trimming and one thing I noticed was there was a lot of pressure right where the spider cracks normally start so I angled the back side of the lens in that area to make them thinner. One of my rubber pieces completely feel apart. I ordered new rubber from Linegear today. I will be using these for my daily wearers for awhile now.
