Don't waste your $ on the EGB2. Get the EG2 for a little more. You've been reading right, spherical lens give you a more realistic vision and the EG2 is wide so you see a lot more.
I tried to save a few bucks and got the Smith Phenom. Wasn't satisfied. Got the EG2 eventually. Go try them on, you'll know what i'm talking about. Besides, almost everyone here at sbing forum has them.
