I'd go with the I/O's. I had Electrics before and they fogged too much. I don't have experience with Smith lenses though so can't comment on that. I have two pairs of Anons and I really like them. My Figments have a red solex and its awesome for every light condition. And I've had nothing close to the anti-fog of Anons.
That thing I do to escape the world and have fun with my friend
