^ and we care because....... and i don't own them, but put them on a few times, and i think they fit really, really large. they fit best with a helmet, but without one, i found them to be to big on my dome.
prodigys are nice. the soldiers are sweet also. it's all about fit. all of the smith gogs have anti-fog coating injected into the lenses so it won't rub off or fog supposidly. i have the spy orbits from last year (haven't changed for this year) and they've only fogged once when hiking. spys are a little more expensive though.
also, the hop up kits for the prodigys are cool but kind of hard to get on. and they're $20 retail which is kind of pricey for three little plastic pieces.
prodigies also have the spherical lense. i like the fit of the smith prodigies and the traids (almost the same fit) so if you have ever tried on triads they fit nearly the same and the vision is awsome
