How much play is in the Nose bridge on a new pair? Also what is acceptable and what is too loose? I think my XX are loose, not too bad, but not as tight as my Juliet pair. Just trying to gauge what is good vs what is bad. been wearing my Juliets with the VR28 Black Iridium Polarized lenses more and more, I like that lens color more and more everytime I wear them.
