Ok. I have been doing a little research on this and need some opinions and comparison pix. I have several pairs of half jackets. I love the fit and style of them. How do they compare to the 2.0 version ? I believe the half jacket frame curves better to the front of my face then a flak jacket does. My problem is no one has 2.0 in stock locally and I read flak lenses possibly fit the 2.0. Thus does the curve of the 2.0 mimic a flak jacket ? Some comparison picks would be nice if someone can post them. I would hate to buy a pair and not like them.
