Wow, awesome advice guys!
@JoeR: I think I may be confusing the meaning of "flat-light" - I thought flat-light is when light appears to come from every possible direction. I used to board mainly at night. The last few times I went in the day, there are no shadows and everything is evenly lit. If that's what you mean by flat-light, I guess my sensor mirror is failing me, unless there's too much light getting through for my eyes to handle.
I'm definitely wanting to get a pair of the Green Sol-X. Curious as to how much 'blue' (if any) it reflects...cause it's a rainbow green...saw some blue reflection on the sides.
Definitely going to check them out at the store.
