I'm trying to find a pair of glasses to add to my penny's and Juliets, something I bit more "mature." I've narrowed it down to the following: Carbon Blades - prizim lens - polarized Carbon shift - Saphire lens Tinfoil Carbon - positive red Tinfoil Carbon - black, non polarized What are your thoughts? I lIke the Carbon blades, but also like the other pairs I mentioned. The Carbon shift sort of have that same "sporty feel" of my Juliets / penny's and I'm wanting somethings different. I also do like the tinfoil Carbon with the positive red as well. Open to opinions.
