I will throw my vote in for the Oakley Wisdoms as well. I also think Bolle makes a great goggle, as I had a pair for about 10 years with one of the original "mirror" lenses. Somehow they got scratched on the plane last year, so I ponied up for some Wisdoms. I got the Blue Iridium lense and it worked great during a really, bright sunny day. The next day it was like blizzard conditions, snowy, no sun, low light, etc and they still worked great. I have been in worse flat light conditions, so I'm not sure how well they would perform, but overall the Blue Iridium lense worked great in both types of conditions. I'm thinking of picking up a H.I. lense though for situations where the light is horrible.
I also bought my GF a pair of the Wisdoms with the VR28 lense and she had no complaints in the same conditions as me. You don't get the cool "mirror" lense effect like the Iridium lenses, but I tried hers on and I couldn't tell much of a difference on either day. I think the Light transmission levels are about the same, but the Iridium is supposed to be better in very bright sunny days, so who knows. Either way you can't go wrong with the VR28 lense or the Blue Iridium. There is also a G30 lense that has a pretty neutral tint but I haven't tried them out.
I did look at the Smith Prodigy goggles and I didn't like how they distorted the sun with the lense. Their "air" vent system was also pretty bulky and the fit was for smaller heads/faces. Mine is on the larger side and the Wisdoms fit great, large field of vision.
