On the search for some new glasses to replace my very old Half Jackets. Was originally thinking of some Flaks, but have come across some Juliets, with Emerald Iridium lens. They are used, but in excellent condition and will come in at less money than the Flaks. I have never tried Juliets and don't know anyone that has any. So I would be buying blind. How would the fit and look be compared to my old Half Jackets?
