Don't think I've seen this on the board yet.....so here goes. Poll is for your all time favorite in any X Metal model. Feel free to share your overall list or comments on your number one pick...here's mine 1. Polished (gets stares EVERYWHERE. Pain in the A** to keep clean and unmarred....but worth it). 2. 24K (the ole one..not the new abomination..if only Oakley made this for Juliet). 3. X Metal (early generations, industrial, otherworld looking...current gen would rank around Plasma on my list). 4. Titanium (many like early generations, I don't...second gen is what plasma should be..a dark industrial silver...almost a Plasma/X Metal hybrid). 5.Polished Carbon (hides a lines a bit...works on XS because of how that frame is designed..makes a dark finish pop enough to be noticed). 6. Carbon (same as Polished Carbon but more subdued...helps pull the color out of Ruby though) 7. Plasma (want your X Metal to like every other metal glass? Here you go. Works decently only with Ice). 8. 24K (new generation...sorry had to include based on my distaste for it). Wild Card: TIO2. Never owned and like the look...but I think it might not get noticed anymore than standard X Metal etc by the casual observer.
