I have 6 pairs of Oakleys, 2 Fast Jackets, 1 Jawbone, 2 Jupiter LX, 1 Ti square wires. Just decided I need to get a pair of X metals. Problem is, I am having trouble figuring out were to start. Do any of the Oakley stores in Las Vegas have X metals to try on to decide which ones to get? Should I just start with Juliets or should I consider something else? Is ebay the go to place to get them?
