I've been "jonesing" for a pair of of the Jupiter Squared. However, I don't have any stores or dealers around that have them in stock to try them on. So, how do they compare in size to the Fuel Cells and the Big Taco/ Offshoot? I have a little bit wider head and the Fuel Cell is a little on the tight side but, I like the way they fit. The Big Taco and Offshoot seem to be perfect for my head and face; it's like Oakley measured me for those frames. Anyway, if you all could help me out a little bit on the sizing, I would greatly appreciate it. Thanks in advance.
