Smith makes a super-bling goggle that has easy-change lenses and a HUGE field of vision. I can't recall the name. I don't know if I would go for Oakley A-frames if I needed to switch lenses out every day. I use them for snowboarding, and changing lenses is a giant pain. I also have to question the use of goggles at around 0C. I know it's more humid in T.O. than here in Calgary, but I'm happy in regular eyewear until -20C. After that they fog too much and I'll just squint a lot.
